Most Gen. Z-ers I know pay very little to no attention to politics. The ones who do are mostly center to center-left, with a few exceptions.
The fact that you live in MA is probably a factor as to why most of your peers are center-left.
This is why I'm excited for the 2020/2024/2028 elections. I can't wait to see how Generation Z votes. I'm going to stick with my prediction that Generation Z will still be overwhelmingly Democratic, but moderately less so than Millennials (since they're too young to remember Bush, so they'll hate the GOP less).
Someone should bump this in 2028 or so to see if our predictions are correct
