It is victim blaming, we are not the reason homophobia exists or that people become extremely homophobic. It is not oppressed people that cause their own oppression, we don’t in some way “deserve” it.
Some aspects of the identity of sexuality may be related to physical and things we cannot control, but at the end of the day it is an identity. If they do not see themselves as gay, they are not. It is not for you to assign an identity to someone, even someone you don’t like. Even if someone might identify as gay outside of these power structures, in here they aren’t. Even if they would be gay, they participate in our oppression because being straight is beneficial to them, not because they “are secretly gay”. If they did homophobia because they were “ashamed” it wouldn’t be helping so many of them get into positions of power
They do it with making gay sex a punchline too and it fucking infuriates me to no end that they don't seem to ever grasp how awful it is
If you ever point out their memes about Trump having gay sex with Putin is homophobic, they'll fucking fall over themselves to assure you that no no, they're not homophobic, but Trump/Putin/whoever else they're targeting is and so insisting they're gay is gonna make em soooo mad (even with a less than 0% chance of them seeing or caring)
