There is evidence that Kurt Cobian was an intersectionalist, and I suspect that he got radicalized into this extremist ideology by 90's third wave feminists, one of the earliest manifestations of the modern Regressive Left.
I theorize that because of his radicalization into this extremist ideology, he had become extremely depressed because of society's non compliance with Intersectionalism, which caused him to falsely believe that women and nonwhites were going to loose all their rights and did not want to live in this dystopic world that never came to pass.
I grew up during the years that Kurt was alive and popular. Kids worshiped Kurt like he was the next Jesus. But the reality is that he was a junkie who got swept up in the popular music of the day. Had Kurt of not died he would of turned out like all the other 90's artists; old, irrelevant, and joining popular causes to try and keep a paycheck coming in.
I know people want there to be an alternative answer so Kurt wasn't a screw up. But that's just not the case. The guy was a junkie who wrote crappy music for depressed teenagers. Sadly too many of those teenagers never moved on with their life and became dysfunctional adults who pine for their youth instead of building something more with their lives.
