The worst part about 4chan culture is how they bully people for things that don't actually matter. It's ok to make fun of someone in a way they're fine with, but the viciousness with which they attack for things that cause no harm is disgusting. I personally believe you should only be cruel to those that harm people intentionally, with people simply disliking something out of taste not counting as harm.

It's tasteless to wear tacky clothing, but people shouldn't care if the person wore it just to make others upset. It's evil to wear nazi clothing to try and anger people, so bullying and ostracizing them is totally justified.

Don't bully people who wear fursuits, bully people who molest animals. Don't bully people who like hentai, bully people who like loli hentai. Don't bully ignorant free market liberals, bully the social darwinists who think people deserve their suffering. Don't hate trans rapists for being trans, hate them for being rapists. Hate people for things that are inherently immoral, and don't generalize to things that aren't.
