Thought they were either perverts, mentally-ill or both. Never particularly hated them or anything, though. Took a libertarian "live and let live" approach, more apathy than acceptance.
Now that it's become mainstream, I've actually met some IRL, and it's a 50/50 mix. Half are really sad, confused, naive, most likely just gay and effeminate men, and abused women with self-image issues, who are getting socially pressured into a self-inflicted meat-grinder thinking it'll make them happy.
The other half are exactly what you'd expect: Loud, angry, terminally online, overly politicized MtFs who only wants to fuck cis women and femboys/other MtFs, and have no plans of actually getting rid of their dick. These are the ones who actually do all the grooming, and it couldn't be more obvious that they're hedonistic BPD narcissists who are doing so for their own sexual gratification. Very much clearly on some kind of downward spiral in life (some self-aware, others not) and are just taking other people with them.
The first half break my heart, and I feel like are some of the biggest victims of clown world. The other half is the closest I've gotten to actually snapping at someone IRL about something (allegedly) political, because they're obviously just predators.
