I don't know why they hate fun so much. For people who claim to love freedom and individuality they sure hate people expressing themselves in non-conforming ways.
I know they claim its because it's "unnatural" but you don't see them complaining about brunettes bleaching their hair to be blonde. Come to think of it, they don't have a problem with women using plastic surgery to have unnaturally large boobs either (unless they happen to be trans)
Hmmmmm :thinking-about-it:
you see, the chuds are actually anti imperialist, and deeply resent the treatment of the global south, and resent the labor abuses it takes to manufacture those dyes before they reach the first world...
just kidding, they're just reactionary misogynists and associate bright colored hair with leftism the same way we associate tattoos of nordic runes with being a nazi.
