What happened to Reddit's politics?

I remember when Reddit was a place you could come for mostly good conversations, but it seems like this platform has been overrun by reactionaries in the last year or so. Check out the post below; you'll see lots of people talking about eliminating Islam and calling Muslims animals rather than analyzing the material conditions that lead to these outcomes. I commented about the U.S.'s history of installing repressive regimes and I got ratio'd. I guess it's easier to settle for a superficial and chauvinist analysis.

So I guess my question is did I miss something? Was there some huge demographic/political shift on this platform, or am I just mythologizing the early days of Reddit?
