Cringe culture is what happens when we let middle-schoolers have free rein online and not discipline them. They bully the "nerds and weirdos" for being "cringy" to seem cool and grown as adults make money off it. I'm fine just having a laugh, but that's all cringe culture boils down to at the end of the day.
These kids eventually grow up (but some sad unfortunate sods never do). These adults then loose their audience and fade away (only few are like solar sands, who successfully updated his content to be about legitimate critical and insightful moving completely away from cringe) or get into a giant controversy and end up destroying their career.
Remember to be more edgy imply the person you're making fun of for something dumb, of something awful with no evidence like a pedophile(cough cough turkey tom).
I'm ashamed of every watching that shit when I was younger, but I was a asocial kid who wanted something to feel better about themselves. Now I cant stand this shit. Make fun of stuff is fine, don't outright insult the person, unless there is hard core evidence of them being legitimately awful (from art thievery to actual with hard hard core evidence of them being a sexual predator) and even then that shit should be mostly dealt with by authorities who can legitimately do something about it or report them.
