I'm not going to try and convince those of you who are already convinced that your prejudice is justified. This is the internet -- you'll always be able to find a bunch of random articles or opinion pieces that support your view. You won't be swayed from your bigotry, even in the face of science, changing public opinion, and just general human decency towards other human beings who are disproportionately victimized and killed by people who hate them for who they are.
But I guess I'm feeling increasingly ashamed of myself for just ignoring it on this site, which I feel is a community I'm part of.
The whole assumption behind this post is that 'we all' disapprove of a charity that supports trans and non-gender non conforming children and their families. There are a lot of conversations and posts on mumsnet like this that normalize transphobia. I usually ignore them, because who wants to get into an internet fight with a bunch of angry strangers? But I get a guilty uncomfortable feeling that by letting it pass unchallenged, I'm condoning it. When I let it pass unchallenged, when I could say something, I feel complicit in your normalization of transphobia.
So I'm not going to get into a fight with you or try to change your mind. If you were open to reason, you'd do that work yourself. There are plenty of resources out there on the internet, and ways to hear from trans men and women themselves.
But I do want you to know this. The prejudices you have, and the hateful things you say here on this site or in real life about trans men and women, and people who are gender non-conforming: it is not acceptable. It's also not feminism. You ought to be ashamed of yourselves.
