its entirely the boomer circlejerk of 'u cant get pink hair job' and chuds want nothing more than to feel included in their parents lead poisoned judgemental attitudes

It's not the particular colors or the act of dying they hate. It's just cultural signifiers that put some people in one group or another. They hate men in high heels except cowboy boots that often have a high heel. It's what just happens to be associated culturally with groups.

Edgy /pol/ kids graduated from being proud social outcasts to inheriting their Christian conservative parents' hatred of nonconformity.

CHUD ideology I theorize is just leftover "popular kid from highschool" ideology in high school politics. This is going to be a bit of a spicy take, so let me explain.

I have noticed that two types of people really like to rally behind the GOP: the first are people who got bullied in high school and they want to take their frustrations out on someone else to assure that they are not the bottom of the totem pole. The former are those who WERE popular in high school, and realized that at the very least, capitalism does NOT give a single flying fuck about how "cool" they were, so by going after the post high school loners, nerds, and goths, they can relive their glory days. Not that this makes them any less pathetic.
