Purity culture and virtue signalling, to the point where they're just throwing random labels onto characters to score woke points and prove how very unproblematic they are, and then attacking anyone who disagrees by making callout posts and accusing them of pedophilia/transphobia/aphobia/being a rape apologist or actual rapist. Stuff like:
"Harry Potter is Indian and Hermione is black, and if you disagree then delete yourself."
"Danny Fenton is canonically trans. Sorry, I don't make the rules. uwu uwu oooowoooo"
"Janeway is demi-gender poly pansexual and in a relationship with Chakotay, who is a trans-masculine poly-romantic demisexual, and Seven, who is agender bisexual homo-romantic. Cishets don't interact."
"Friendly reminder that [insert screenname here] is an actual pedophile because they ship Kataang."
"[insert screenname here] has a bad Steven Universe headcanon and is evil, but you should definitely not dogpile or dox them. *wink*"
