I skimmed through this article too! Didn't have much time to read it, but what I saw was pretty great.

I might recommend this channel to you (this is just a nice example video of what it's about, recently).
What I like about it is that Tim, being a rational center-left liberal, is a living, breathing example of just how far the left has been radicalized in the last 20 years (well, that and his great views/videos, of course).
