nobody on this site is ever going to agree about whether or not cisphobia, heterophobia, racism against whites, or sexism against men exists until there is some kind of rigid definition in place. Nobody is going to get anywhere when all we’re doing is arguing about definitions.
For example, or…
Fuck off. Cishet white men have never been and will never be oppressed for their race, gender, or sexuality.
You seem to have missed the point of the OP completely.
It was not stating anything about the existence or lack thereof of any oppression whatsoever. It was rather stating that this entire argument is constituted solely (or, I guess, mostly) of one side claiming that heterophobia doesn’t exist due to the lack of oppression and one side claiming that it does due to, well, (albeit extremely rare) hate of heterosexuals; the only reason this debate exists is because no one can agree on whether oppression is required for heterophobia to exist. Which, in fact, if anything, acknowledges that cishet white men are not being oppressed, as otherwise whether our definition requires oppression doesn’t matter.
OP is literally whining “but what about teh cishet white men?!?!”
OP does not make any references to cishet white men. OP only states that people can’t seem to agree about what qualifies as reverse racism, heterophobia, etc.
