>Ignoring that social trends and constructs have an effect on how the world functions

His acknowledgement of that is a founding principle of his philosophy.

He doesn't oppose all abstraction. He knows full well to get rid of all social constructs is to get rid of all thought. He rather wants as many people as possible to recognize and embrace the fact that all actions are done for an agency that exists beyond identity.

If you read his book you'd know he's completely aware that this perspective has become contingent on historical processes.
