We?
idk this person, and I only know what you have written about them. There might be a lot more nuance, or not. But this post is not nuanced, probably too hastly written, without thinking twice about what you wrote and you do not seem to have the intentions you suggest you have. I can't believe you wrote this because you want to "save the trans community from crazy fakers" or whatever.
I assumed that. There is the idea to exclude groups from the trans community to make the community not look worse (to cishets) and to not waste time helping the other groups. I.e. saving the trans community at least effort. I assumed that is your (at least suggested) reason. But instead you don't care about trans people (maybe neither in a good or bad was) and just don't want people like the person you described to be helped by anyone. Or you even don't want them to exist at all. Is this assumption correct?
Also some people are crazy, big deal
