TERFs, on a fundamental and very literal level, genuinely don't think (cis perisex) women can ever do anything wrong. You can clearly see this in how they talk about cis men and trans women: they say "men" are, essentially, biologically wired and socially encouraged to be sexually violent predators towards "women," who are apparently never encouraged to be sexually violent in any way, and that's one of their many reasons as to why they think trans women aren't women, because "real women can't be [sexual predators.]" When confronted with the fact that this obviously false to any normal person, they say, "It's not possible for women to rape men because men hold such an overwhelming amount of privilege over women that a woman sexually assaulting a man wouldn't be nearly as traumatizing as the inverse situation, so it's not comparable to call both of those situations by the same word. Also men are basically robots who don't feel pain anyway, and if they did, they'd deserve it lol."
... HOWEVER, when a gay trans man dates a cis man, they immediately drop their whole "women are precious little angels who can do no wrong" act. Suddenly it becomes "You're a predatory homophobic woman forcing gay men to have sex with a female," even though they claim women can't be rapists and the feelings of men don't even matter because they deserve to be hurt for being male. And that's kind of my whole problem with the idea that "TERFs love trans men/TERFs only hate trans women," because when you really analyze it, you notice they just... don't treat us and talk about us the same way they talk about fellow cis perisex women. Everything that applies to "women" doesn't apply to us when they want to villanize and misgender us. They claim that they love us because they feel they have some inherent kinship with us, but when it comes to trans men and cis men, TERFs will always side with cis men no matter what.
TERFs do not love trans men, just like abusers don't love their victims. They "love" the idea of being able to force us to detransition so we can be "normal women" again. If someone loves the idea of trans men detransitioning back into a cis perisex woman, then they don't love trans men: they only love cis perisex women.
