The worst part is no-one cared, fucking "they'll grow out of it" and now everyone is suddenly in shock. When I talk about it to my friend today he's even in fucking denial about it, "Oh they didn't actually mean that, it was all jokes".
Most edgy teens do grow out of it. I roll my eyes at embarrassment at some of the stuff I wrote in college, and high school me was even stupider.
But one difference in my high school years (in the 90's), edginess wasn't inherently politically coded. Some of it was racist, sexist, or homophobic, but plenty of the targets were also Republican constituencies: rural/small town people, Christians, fat people, old people, prudes, etc. In a conservative suburban area, jokes about abortion, sex, drugs, etc. were often designed to elicit shock and disgust.
I think we've seen a cultural shift in which edginess is seen as right wing in itself, in part because the right, which used to get offended at things like Harry Potter and Howard Stern and Disney movies, has fallen in line with edgy Gen X comedians who somehow didn't grow out of it, and made room for people who smoke weed and mock the Bible.
