band together and hate a specific cause.
The thing with Gen X teenage nihilism was that the only cardinal sin was actually having a strong opinion. There wasn't much room to hate on anything, because actually hating something showed that you cared too much, and that wasn't what we were about.
Gen Z seems to be much more willing to embrace negative emotions and acknowledge that they care enough to hate. Whether that's a better or a worse thing, I'm not sure.
