I had kind of been sick of trans/'queer' ideology for a few years already by this point, but what really shocked me and pissed me off about it recently was when a few months ago my younger sibling (early teens) expressed the opinion that people who refuse to date trans people are horrible people. I was shocked and wondered where they had heard this, because there was no way they came up with this on their own… Needless to say, I told them that they had the right to reject anyone for whatever reason they want and they should not be labeled bigoted or a bad person for it. The fact that children and teens (especially LGB ones) are being groomed into this mindset is abhorrent to me, and I hate what the TQ+ are doing to the rest of the LGB community and what transgender ideology is doing to women's rights. Around the same time, there was uproar on social media coming from some of my former classmates who were offended by JK Rowling's "transphobic" essay, but hadn't seemed to have read it themselves, so I read it, thought it was reasonable, started looking, and wound up here.

So, all in all, I wouldn't say there was one specific thing that was my "peak trans" moment, it was more of a slow burn with a lot of stuff chipping away at my initial support for trans ideology (trans and non-binary friends and classmates, pansexual snobbery, noticing r/actuallesbians was like a third transbians, every LGBT online community being mainly about the T, stopping believing in the concept of gendered souls, lack of evidence for gendered brains, trans-women in women's sports, TRAs denying the differences between male and female socialization and their response to Chimamanda Ngozi Adichie's comments, "genital preference" discourse, the increasing obviousness of how reliant on gender stereotypes this shit was, TRAs' denial of biological sex, pronoun madness, non-binary obviously just being an attempt to escape misogyny, insistence on using gender-neutral language in sex-ed which would make it inaccessible to those who needed the info the most, how liberals had a religious fervor about their support for trans ideology, getting corrected in class by a teacher and a liberal friend that sex and gender were different, seeing kids getting corrected in class on classmates' pronouns, when I first saw the fearmongering about Drop the T being a hate movement when it made perfect sense to me and didn't seem hateful at all, the "you owe your rights to trans women" shit, the highjacking of feminism, the gaslighting of saying that the vast majority of transgender people are nice people and therefore the problematic and violent ones don't matter, logical inconsistency, learning about how harmful puberty blockers were to children, finding out about the astroturfing in the trans movement and seeing how they were deliberately holding LGB rights back, TiMs getting women's scholarships and political seats, the high amount of TiFs in an online eating disorder support group I was in, the pathetic state of my school's GSA, "queer sex" guide articles floating around talking about PIV sex being a type of lesbian sex, noticing the grooming in all this stuff, noticing how conservatives I knew were more likely to be supportive of/sympathetic to trans than LGB, seeing how transgenderism ran in certain social circles, observing how transgender people behaved more similarly to what was typical of others of their biological sex than their gender identity, the likes of Danielle Muscato, the pressure to be open to dating trans people, the fact that I didn't have a sense of gender identity like they insisted I must, the insistence that trans people were the most oppressed group in america despite nothing to really back up that claim, the beggars on social media, the way gender identity kept constantly being likened to sexual orientation, and so much more.), but to hear something that reeked of such obvious grooming from my beloved younger sibling made me just 100% done with this shit.

N.B. My sibling isn't a "they", I just used gender-neutral language and an approximate age to refer to my sibling to avoid identifying information.

TL;DR: Younger sibling said people who weren't open to dating trans people were horrible people, whole thing reeked of grooming, said fuck this shit.

PS I'm probably younger than most of the people here and this transgender ideology stuff has been around all throughout my teenage years, so it's interesting reading stories from people older than me here to get a different perspective on the whole thing!
