Harmful? Fucking hell, it wasn't the fucking T causing harm it was TERFS like Robert Galbraith alias JK Rowling who chose the name of the individual who pioneered the abuse known as repairative therapy. And only made Dumbledore gay to pander. She allies herself with religious right and to boot the goblins are very much described in same manner Christisn Identity describes Jews. Keeping her as one of your heroes is far more harmful.
But you need more. OK. Quiverfull, Huckabee, various homophobes call anyone LGBT (and hell removing the T they still would) call you paedophiles and abusers. Not one TERF spoke against that, instead further persecuting transgsnder folk. This hurt your cause so much fucking more on two different levels, first not defending yourselves nor calling them on blatant hypocrisy (which triggers them. Just look at our chopurcockuv in any aliases he used on FSTDT. Others would have same reaction) which would be the best way to help your cause and hurt theirs but also you throwing T under the bus means one less to help when your usefulness is at an end. And if you play the "you're cishet. Shut up male cishet." Well now I have no reason to defend you AND it would be your doing. You cast off the transgender community thinking you're doing right but at best you're useful idiots. At worst you're enabling those that persecute you an easier time doing so. And when you beg for help, I'll be there. To help those who tried to help others. As best I can. I'll look at you and say no.
Then super straight and supergay. The latter. You think anyonees superstraight supports you, they don't. It is Russian propaganda. Nazis assholes ate it up. You're just useful idiots.
