LGBTQ+

Your quote reminds me of one of the biggest misconceptions about Judith Butler's work who wrote so much about gender....

People constantly misquote them and say that Butler wrote that "gender is a performance" and assume that Butler meant that gender is fake.

What Butler Butler actually wrote is that "gender is performative", ie. it involves a performance that communicates our gender identity to others without the performance being the end-all-be-all of gender.
