The issue of "I hate all men, including trans men" and the double standards of cisnormative feminism.
I finally realized how to articulate my issue with statements like this and the horrible double standard that we are held to by cis society. And in this case, cis feminism.
The hatred of cis men is usually performative, whereas their transphobia tends to be real and unexamined.
I have known cis women who say things like this, then proceed to stan cis male celebrities or have hundreds of M/M fics bookmarked on ao3 with not a single one of them featuring a transmasc character. They clearly do not hate men. They love men.
When I've called people out on this double standard, I've been accused of being an MRA, and I've seen others accused of acting like incels. What people don't understand is that I do not have a problem with statements like "I hate men" or "men suck." My problem is that specifying that trans men are included in your hatred of men - whether you are serious or not - is not the "gender-affirming" allyship people seem to think it is. The fact that they're being "gender-affirming" is just a flimsy excuse for needless cruelty directed towards trans men and transmascs. I understand a lot of these people don't actually hate trans men and just think they're being cute, but it shows a distinct lack of self-awareness of their own cis privilege. If I said, "I hate all cis people, including women," people would probably take issue with that, and that would be perfectly reasonable.
So much transphobia directed towards transmascs and trans men is couched in terms of "hating all men." But plenty of cis women love men, too. Why is it so much more common for the "gender affirmation" of trans men to be an expression of hatred and not an expression of love?
