Unfortunately for them, undermining the materialist project has always implied an anti-foundationalism that ultimately kills their own project. They cannot peddle any type of physics, classical or quantum, without assuming the key principles of materialism and scientific realism.
Kant defined 'Idealist' as;Don't be too hasty and simply condemned 'idealism' in general.
Your views of philosophical realism is Empirical Idealism.
Therefore if you condemn idealism in general without qualification, you are also condemning your own philosophical views, i.e. Empirical Idealism.
Here is how Kant view your Empirical Idealism; [mine]
The term 'Idealist' is not, therefore, to be understood as applying to those who deny the Existence of External Objects of the Senses,
but only to those who do not admit that their Existence [of External Objects of the Senses] is known through immediate Perception, and
who therefore conclude that we can never, by way of any Possible Experience, be completely certain as to their Reality. A368
What Kant implied above is the Philosophical Realist also a Transcendental Realist, Empirical Idealist is only acquainted with the sense-data of a supposedly real object, thusThe Transcendental Idealist is, therefore, an Empirical Realist, and allows to Matter, as Appearance, a Reality which does not permit of being inferred, but is Immediately Perceived.
Transcendental Realism, on the other hand, inevitably falls into difficulties, and finds itself obliged to give way to Empirical Idealism, in that it regards the Objects of Outer Sense as something distinct from the Senses themselves, treating mere Appearances as Self-Subsistent Beings, existing outside us.
On such a view as this [Empirical Idealism], however clearly we may be conscious 1 of our Representation of these Things, it is still far from certain that, if the Representation exists, there exists also the Object corresponding to it.
In our System [Transcendental Idealism aka Empirical Realism], on the other hand, these External Things, namely Matter, are in all their Configurations and Alterations nothing but mere Appearances, that is, Representations in us, of the Reality of which we are Immediately Conscious. A371
"it is still far from certain that, if the Representation exists, there exists also the Object corresponding to it".
Where the philosophical realist [you] reify that supposedly-real-object, then you are clinging onto an illusion.
As I had stated, why philosophical realists [like you] are reifying, chasing and clinging on to the illusion is due to desperate psychology within.
On the other hand for the Transcendental Idealist aka empirical realists, external matters are the the Reality of which we are Immediately Conscious and entangled and embraced as one in unity with reality.
So from the above, the philosophical realists also a Transcendental Realist, is an idealist, i.e. an Empirical Idealist.
