Gosh, you ask big questions, Age. I don't really know where to start.
Let me see...ummmm.....OK, last time I looked, my genitalia ( I'm a cisgendered, straight, non-intersex, male) it appeared VERY different from my wifes'. Last time I looked I didn't have a large pair of tits, but my wife did. Also my wife (a cisgendered, straight, non-intersex female) has all the anatomical, physiological, biochemical, hormonal etc, gear need to be able to get pregnant and have a baby, and she has had a baby - mine. I'm pretty sure that I (a normal male) can't do that ( that is, get pregnant and give birth to a baby I mean). So that's a very big difference between men and women, isn't. I don't ever wear pink dresses or put on make-up (like lipstick and mascara or walk around in high heels carrying a designer handbag, but my wife does stuff like that all the time. There's another big difference.
BTW, I hope you are not going to begin questioning me about sex/gender issues to do with(1): male and female homosexuals (2) persons who are medically diagnosed "intersex" (3) Transgender individuals with professionally diagnosed gender dysphoria (4) persons who identify as bigendered, genderqueer or agender and so on. These individuals are afflicted with medical and/or psychiatric disorders and I am not a qualified doctor of any kind. They have my sympathy, as these disorders can cause material impairments, there is good quality medical and psychiatric treatment available for these conditions and I hope that they take the opportunity able to avail themselves of the appropriate professional services. Adult individuals in categories: (1),(3) (4) have mental/ psyschiatric disorders. In the US the American Psychological Association (APA) and the American Psychiatric Association no longer officially regard homosexuality as a mental disorder. The fact is that it IS a legitimate mental/psychiatric disorder and these two organisations have buckled under political pressure from the liberal political establishment to lie. (If you want evidence of this read the following free access literature paper: Robert L. Kinney III; Homosexuality and Scientific Evidence: On Suspect Anecdotes, Antiquated Data, and Broad Generalisations. The Linacre Quarterly, Nov;2015; 82 (4) 364 - 390.) Intersex persons primarily have a medical condition, as opposed to a mental/psychiatric disorder, though they may often demonstrate abnormal/harmful sexual behaviours/attitudes.
Also men and women have very different brains, they think very differently. If you haven't worked that one out yet, Age, I fear there's little hope for you in terms of engaging in a stable, meaningful, harmonious etc long-term heterosexual married relationship.(BTW, I say "married" and not merely cohabit, because I'm a traditional Conservative and the institution of "marriage", still has very important meaning for me. It is an official/legal state of union between a man and a woman as husband and wive. It begins with a sacred promise they make to each other (before God) to always be faithful, to honour and love each other, to support each other through thick and thin literally until death separates them. That still means a lot to me. To sum it up in modern kids' language It's very hard-core, but its VERY kwell at the same time).
To continue. Just this month (19th April, 2019) a scientific study was published in the literature (in a "high impact" Journal) that is a major "game - changer". I'll give you the reference right now so you can check it out for yourself:
M.D.Wheelock, J.L. Hect, E. Hernandex - Andraskey, S.S. Hassan, R. Romero et al; Developmental Cognitive Neuroscience, "Sex differences in functional connectivity during foetal brain development", Vol 36, April 2019, 100632.
This investigation has found that significant ( some would say "dramatic") differences in the ways that the brains of male and female foetuses develop in utero (i.e. in the womb, prior to birth). The authors of the research wrote that "The present study demonstrates for the first time that the development of foetal brain Functional Connectivity ( i.e; the development of of the neural connections between different parts of the brain) varied with sex". The authors concluded that the foetal brain networks they observed were very likely to be "building blocks" for brain development throughout the baby's life.
This study will have an absolutely seismic impact on current research, scholarship and teaching in a number of academic disciplines, in particular, the social sciences, psychology, feminist/womens' studies in the Western academy where leftist "progressive" academics have, for decades, argued that gender is a social construct. They have done this out of fear that should they not toe the "Stalinist" political correct line they will be branded "sexists" and lose their jobs.
Well, now they have been placed in tricky situation, because the study will undoubtedly be followed by similar research that will demonstrate the same kind of findings. We now have indisputable, empirical evidence that there are conspicuous differences in brain function between boys and girls at a stage of development when a baby has NOT YET BEEN EXPOSED TO SOCIETAL INFLUENCES. And more such evidence will not follow apace. There will be a lot of embarrassed professors in American social science faculty struggling to explain why they wilfully and persistently lied ( and that is EXACTLY what they did) about gender being a purely social construct, when they knew full well even from the scientific research that preceded the study I am discussing that this thesis was almost certainly false !
Anyway, with this new study, we now know that the human brain is gendered prior to birth. That may be extremely politically incorrect, but it is an EMPIRICAL REALITY. WE now have evidence that male and female are, so to speak, "of God". They are hard-wired. They are innate.
Understandably, it is not yet clear to the neuroscientists what exactly the gender differences in brain function might mean in terms of how brain activity relates to mental events and states in the phenomenal domain, that is, in diurnal human experiential consciousness How precisely it is that the brain mediates the process of rational cognition or feelings like emotions or the regulation of impulsivity or propositional attitudes/intentional content, or reasoned deliberation or the experience of moods and so on and so forth. WE do not know because to date no one - no neuroscientist of Philosopher of Mind - has managed to solve the so-called "hard problem" of consciousness (aka the Mind-Brain problem).
So, in conclusion, the big news is that the category of "boy" and "girl" is now officially meaningful. They are NOT a mere performance or a social construct. They are clearly meaningful and real prior to birth.
On the 1st April, 2019 the New York Times published an OP-ED by one of those leftist, politically correct, female academics that make my blood boil. They are very destructive individuals, peddling a degenerate political ideology (socialism) and are responsible for a tremendous amount of social damage in the West. The one in question is a Dr Carol Hay, a professor of philosophy at the University of Massachusetts - Lowell, who was endorsing the social constructionist theory of gender, calling gender "fundamentally a performance" based on and learned from social systems. Of Dear, it seemed that poor Dr Hay hadn't read the latest scientific study yet, and when she was confronted with the fact tried to scrabble her way out of being a long-time profession preacher of bullshit, by saying that when it comes to gender she "tends to be pretty critical of the sciences because I think it's often motivated by a particular political agenda, as all science is motivated by a particular political agenda."
Yeah, right. How about doing the right thing and admitting there is hard evidence that confirms you'r crazy,feminist theories of gender have just been proven to be totally FALSE - totally WRONG - 100% BULLSHIT
If I had time I could give you some examples of Ms Hay's beliefs about gender in some detail, but I don't. So you'll just have to trust me when I say trust this woman is completely off with the pixies - a certifiable head case.
