Memes

Not sure where you live, but millennials and Gen z generally have more liberal views than conservative ones in the US, as far as I'm aware. Here's a couple links to Pew Research Center, first is a number of statistics regarding political stances between generations (doesn't include gen z) and the second is specifically about how Gen Z compares to older generations in political stances.

That’s because the ones that moved left also moved to the coastal cities.

Where I live

Where is that?

That definitely doesn't match what I've seen, in Canada (both Sask and Ontario), nor what polls I've seen (eg, on topics like LGBT acceptance).

Note that the alt right are often the loudest (at least on a per capita basis). I think this can skew perception on how common they are, since they are over represented in online comments and there's some kinds of online comments that are completely dominated by the right (to the degree where "don't read the comments" is a meme in leftist circles).

Location definitely matters, too. Cities are way more accepting than rural or suburban areas. If you're in a rural or suburban area, you have my sympathy. I grew up in a rural area myself and it was awful. I think many people (myself included) are purposefully fleeing shittier areas. That means progesssives not only migrate from rural to cities, but also from shitty provinces/states to better ones.

But even within the same cities, I've perceived younger people to get better over time. I'm pretty hopeful for gen Z, which seems better than my generation (millenials) were at the same age. I just wish we didn't have to wait so long for progressives to outnumber regressives.
