I have signed up again after a long pause, particularly because I wanted to share this in the light of current events, and because questions about Queer theory were asked (I lurked on here), and I just saw a revelatory talk about it on you tube.
Derrick Jepsen boils it down to:
violating social norms, in order to subvert power structures.
You could argue that how the Soufragettes acted was 'not normal' at the time, same for Gays&Lesbians with their Parades, and it indeed worked and freed them. You could make the same point for people who defy gender norms (trans umbrella), to subvert the prison of gender expectations. (Of course, most would argue that this is fine, as long as women's rights are respected. Queer theorists might however argue that the fact that women's rights are a social norm now means, women now are the oppressors).
However, Queer theorists basically say every social norm is an expression of oppression and must be subverted - which also leads to the rationalization of paedophilia. Here is an interesting summary of Queer theory's position on paedophilia in form of a quiz at a uni lecture by Jepsen:
(I recommend the whole lecture, also about anarchy and mysogyny. the paedophilia section as a whole starts at 1:51:30: .
I found that quite enlightening and thought, I'll share it on here.
