TERFs brazenly use their own slurs, TIF (trans-identified female, aka a trans man) and TIM (trans-identified male, aka a trans woman). They don't care at all about respecting each person's chosen terms, they only care about ideology and enforcing their viewpoint.
I'm very frustrated by the apologists saying, "well, cis people don't necessarily identify with that term and we should respect that". It's not so simple, what term would they like us to use instead? They never offer one. They want the absence of any term, because they want to enforce an ideology where only they are normal. So they can make up any mean words against trans people that they want, but we can't even factually describe them with a neutral term?
