Look, if there are a group of gay men who disagree with GC feminism so strongly, then there is nothing stopping them from breaking away and forming their own droptheT movement. By all means they can do the work of developing their position statements, lobbying governments, having conferences and getting all the death threats and rape threats like GC feminists and radical feminists do on the regular. They can look for allies wherever they think they're going to find them, though if they don't want to work with feminists then all they've got left is the conservatives who don't like transactivists, really.

You're looking at this through the wrong lens. Radical feminists built the resistance to trans ideology, because radical feminists were the only ones who cared about this issue while it was still only affecting a small minority of women. The radfem critique of trans ideology is only one tiny part of a much bigger political framework that is about looking at all the ways women are oppressed, but that tends to get forgotten because trans has become such a big issue. As the influence and toxicity of the transmovement has grown, a greater cross-section of people have stumbled across radical feminism precisely because radical feminists were the only group who had a functional critique of the trans movement. More or less, GC feminism grew out of that. A movement with a broader appeal that is still mostly founded on radical feminist political frameworks. Though naturally as the size and popularity of the movement grows, the understanding of the politics often gets watered down and distorted. Radical feminists and GC feminists are the ones who have done all the heavy lifting here. So it's laughable for a bunch of dudes to come along and threaten they will take their oh-so-important non-contributions elsewhere if feminists don't change our entire movement to suit them. My response would be - okay, off you go, don't let the door hit your ass on the way out.

Now, as seen in something like the LGB Alliance in the UK, clearly, there are gay men who are capable of working with lesbians who are radical feminists, and clearly there are lesbians who are radical feminists who are willing to work with and ally with gay men. That group was founded by a group of extremely experienced political activists who have been around for decades, and who made great contributions to the original LGB rights movement, and the 2nd wave feminist movement. If I'm going to look for a group to get behind, I, personally, would choose to ally myself with a group like that, who, as their founding principles have a commitment to advocating for homosexuals, as well as explicitly articulating a feminist politics and recognising how lesbians are affected by both homophobia and sexism.

But if there are a group of gay dudes who think the winning strategy is to built an anti-feminist movement that focuses solely on being transcritical, I'm not going to stop them. Any woman who wants to join that movement is likewise welcome to do so. But I sure as hell wouldn't be.
