As a Gen Z, I can tell you honestly that there isn't really a definable Gen Z trend at the moment. We're all over the place, politically. Most of us don't even care that much about politics because most of us are still just teenagers or at most, like myself, very young adults. The very oldest among us are like 22-23 years old. The youngest of us are about 8 years old. Those of us that do care about politics, well, in my experience it's more polarised than what seems to have come before (whether or not that's actually true).
Centrism is much less popular than I think it is in older generators, thank God. Many of us have veered leftwards, many of us have veered rightwards. I don't think either really holds sway more than the other in general. In some places there's more of a leftwards leaning, in other places a more rightwards leaning. SJW politics aren't very popular either, that definitely seems to be a Millennial thing. That's not to say there are no SJWs in what I've seen of my fellow Gen Z-ers, of course there are quite a few, and definitely more than there are in Gen X, but substantially less than among the Millennials. If many more were to become SJW/idpol-types, I'd already see signs of that in people the same age as me, even slightly younger, and that trend is decreasing in people I'd say born between 1998-2003, from what I can tell at the moment.
Where I live, the rightwards shift is much more prominent than the leftwards shift, but I do go to a Catholic school which is predominantly white British or Irish, some Polish too, so you see it's very dependent on the environment. There's another place I go to to do one subject which is a secular Sixth Form College and there the leftwards shift is dominant. This other place is a very multi-cultural environment with white British together with people of various Asian and African ethnic backgrounds. There is also a significant gender divide with boys and men much more likely to have rightist beliefs (if they're white), and girls and women much more likely to have leftist beliefs (non-white men too). It's obviously not completely cut and dried like that, but in general, that's the pattern, a greater polarisation. Maybe some other Gen Z-ers on this forum might disagree with me, but I'm just speaking from my own experience about what it's like where I live at the moment.
