Zacs, look up Rachel McKinnon, Fallon Fox, Hannah Murphy, Karen White... just off the top of my head. To say that others aren't or won't be affected, is clearly not the case. There are hundreds of examples i know of, and no, they are "lost" quite quickly.
Let's be honest... if it was no threat and made no difference to anyone else, the majority wouldn't care (some would still, I'm sure).
But you don't seem to have really researched this much.
By all means, let transgender people move forwards to happy, safe, healthy lives- but currently, they are moving sideways and trampling over female rights and safety instead. We don't need to go back 500 years... let people live, but while it's being at the expense of women, I can't see it will work. And even if ttt isn't personally affected, he may still have female friends, relatives etc. It affects us all.
