First of all, I’m so sorry that happened to you. The way people turn against you when you stop playing by the rules sucks.
Second-there are so many reasons why people wouldn’t want to follow these gender norms! Being trans, being disabled physically or mentally, being traumatized. The idea that it is normal and healthy to exaggerate our sexual characteristics to the point we are impersonating ourselves, feigning the appearance of sexual interest to simply behave appropriately-what is that?
