> People that think "Gender is a performance" and that there are "basics" that have to be learned have clearly been steeped in post-structuralist thought

As someone who knows a thing or two about post-structuralism, I also know many, many people who think "gender is a performance" and know absolutely nothing about it. Your assumption that everyone knows the entire intellectual history of the ideas they espouse is a bit wrong.

Furthermore, while it's true that Butler et. al are some of the more prominent proponents of 'gender is a performance', one could easily believe that gender is performative for a different reason. A implies B does not mean B implies A, and all that.
