I think it's activists. Trans people should be treated with respect and have the right to be who they are without harassment or prejudice, but others have rights too. It's the activists who push this stuff onto children, and they have enabled men insisting on gender self-declaration so they can access the Marks changing room potentially without being genuinely trans at all, and the activists have also made it possible to infiltrate women's sport.
Normal trans people are not the issue, it's these activists who have zero sense of proportion and care nothing for anyone's rights except their own. If I was trans I'd still be appalled. In fact I know a trans person who IS appalled. The activists won't be happy until they've obliterated all and every sign of male and female in our society.
I remember when I was young, there were several trans figures around and they just got on with their lives. There was a skater at the ice rink I used to go to as a young teen, and he was called Stephanie but was a he. He was probably around 18 but seemed really old to me. We just accepted it as normal, and he was normal. He wasn't talking to us about his gender identity or his gender surgery or how his penis was going to become a vagina.
My friend was asked out by a trans man in her office. Again, he just lived his life. And Haley in Coronation Street was a trans woman, married to Roy, and people just accepted it as normal. I never heard anyone discuss the character, and Haley wasn't some huge trans icon. Of course, that was before social media and before children could access said social media, and then of course endlessly discuss the things they see.
The activists have done their best to destroy childhood, women's sports, women's safe spaces, and to confuse the language. If they cared about being clear instead of just imposing their will on everyone, they'd have campaigned for ze and zir, not they and them. I don't think they're trans activists at all; they don't care if they make trans people look as bad as possible or if their dogma creates problems for them. They're just anarchists by another name.
