It's like, a person disagrees on a leftist issue like do non binary genders exist (a matter of sociological theory)
Go ahead and tell all the non binary people that they actually don't exist, it's just all sociological. Is this the new "it's all in your head" stuff they used to tell gay kids back in the day?
Not even going to get started on the transphobia in your comment, trans kids shouldn't get the medical treatment now because some countries are banning it. Great logic, it's not like countries have ever prescribed incorrect medical treatment to LGBT people before. Alan Turing? Who's that again?
What the hell is wrong with artificial hair colours? I'd never dye my hair an unnatural colour myself, but it's a cool look on some people. What is the "blue haired leftist stereotype?" Is it some right wing American meme?
In the same way that Christianity or Wicca are real
it's also real that there are people who don't believe than one can be non-binary
So if someone holds the view that they don't believe it's possible for a person to be a Christian even though there's millions of people that call themselves Christian do you think that means the question of whether or not there are people that are Christian is up for debate? That's insane.
Yeah, they really showed that we will call someone a Nazi after they come out of the gate equating us to Nazis and then start saying transphobic shit and going off about blue-haired SJWs, we're so owned by this, somehow.
