Perhaps people who think that women's rights are important think that the issue isn't a single issue, but multiple issues all directed at women and girls.
What actually happens is that the activists pressure the government to address issues that affect trans women and this is to the detriment of actual women.
So everything and their uncle having to be 'trans inclusive' and they mean 'inclusive of males' not 'inclusive of women who think they are men' otherwise they lose the funding. So it destroys the original aim of the thing that was originally designed to benefit women/girls. We get this over, and over, and over, and over again.
It affects the thing, the access, the risk, the funding, the safety, the ability to speak out about it, the lack of press coverage, and thus is covers everything from the decision to the people now missing out because they have to self exclude. And when the whistle is blown, nobody gives a shit enough to even report it.
It isn't a single issue it is a multi level issue. It even affect us being able to know what we mean when we say 'women'. We don't mean 'men who say they are women', we just mean women.
