I'm a Gen Z male, from what I can tell it seems like older generations tend to rely more on cable or traditional news outlets while younger generations tend to get their news from social media platforms like Instagram. Cable news tends to be more corporate and "normal"/consistent, while Instagram tends to feed news from a larger variety of sources that tend to be more anti-corporate and radical, but those sources also tend to optimize for very short bursts to get the point across quickly so the user can quickly move on to the next piece of news, and there's also quite a bit of low effort content and reposts and misinformation and that sort of stuff. So I think it's social media that's the main driving factor in causing Gen Z to be more radical - which in some ways is a good thing since they have more awareness of the events in Palestine (and radical leftism is based), but the platform can also put them into far-right fear-mongering bubbles and cause serious problems.
