Gen Z political "activism" to me seems to be mostly settling up a Twitter account with an anime avatar and "they/them~BLM~ACAB" in your bio and then posting about being angry that white pop singers are wearing clothing that is associated with a non-white ethnicity or something along those lines.
Meanwhile Millennials include AOC and made up a lot of the activist core for both of Bernie Sanders' campaigns for example.
Yeah, and don't get me wrong, it's okay to use the Internet as a medium for some organizing. But the mentality is that "me and my cadre of 4 lunch table friends alone will save the world through ironic memes". That's not organizing. You're not going to get anywhere by doing that. I recognize that some of that is a reaction to the perception that the Millennial right and particularly left sold out to the establishment and became status quo cheerleaders, but Gen Z's refusal to get out there and work with similarly minded people will be their downfall. The anti-social bit is a flaw I recognize I share with a majority of my generation and it's something I'm working on, but the ones who embrace that (for politics at least) are just embarrassing IMO.
Go to any DSA meeting, anti-war march, whatever, it's all a bunch of Yukon Cornelius-looking Millennials.
