It's hard to talk about this for myself as a trans woman, and especially for cis gays, as liberal queer ideology has taken over the discourse, but it's worth having more queer people speak up about it so we can develop a language for it that leaves things open to good-faith debate.
I'm not against blockers to delay puberty until someone is old enough to develop an informed understanding of themselves, but it's definitely the case that kids are overexposed to a monolithic queer culture that puts frivolous acts of expression on the same level as life-altering changes to your social and physical self. A decade ago things were pretty different—you'd seek out an online community and read a lot of Q&A, stories, and _advice on psychoanalyzing yourself responsibly_, which I don't see much of anymore in trans spaces.
It's not just cis gays, but many trans folks as well, who are seen as regressive for having opinions divergent from what you see on progressive new media, Twitter, etc. Talking about something like this, or defending pronouns as something defined by others that can't be "wrong", or even something as milquetoast as signaling my disinterest in being invited to orgies, will get me at least a confused look from your typical urbanite queer, and possibly get me called a transmisogynist. For a gay man's perspective, Tim Dillon has spoken about this a lot, and folks like him are much more common than you might think.
One thing I definitely disagree with the author on is the idea that the current wave is about abolishing gender, in contrast to previous waves focused on sexual liberation—for one I don't get a "sexual liberation" vibe from the era of gay marriage legalization, and for another I see the present movements more as sexual-accelerationist, i.e. exploring sex and gender with such fervor that they're eroding its social utility and finding new ways to preclude healthy development of relationships and communities. Younger trans folks I've been with are so sexually liberated that it turns into narcissistic hedonism and you can't even be sure they're in the room with you when you're having sex.
