There’s very little daylight between the political Left and social constructionists. Claims that gender is a societal fabrication, that dissidents of that perspective are only furthering their own arbitrary power, the belief that compliance with dictats from identity groups is mandatory etc — these are all postmodern ideas that have entirely consumed Classical Liberalism as the philosophical foundation of the Left. 

You say you’re not on the Left but it’s a moot point in a way since your belligerent constructionist ideas are effectively synonymous with the Left.
