I finally put him back on ignore, so I don't know what he's arguing, but with red circles, there's clearly something in the extramental world with respect to electromagnetic radiation and spatial extensional relations that we can all be wrong about, and that we can discover, whereas that's not at all the case with moral edicts or stances or whatever we'd like to call the supposedly extramental moral whatevers.
The description of any physical quanta requires an appeal to Mathematical realism. It requires the reification of real/complex numbers as physical objects. There is nothing "beneath" our "fundamental particles" - it's just mathematics!
What or where are "electromagnetic waves". What's a "wave" anyway? Complex numbers?!?!? Oh! Another mathematical reification.
Clearly this idiot hasn't looked deep enough into the matter.
