This is pretty much exactly where I'm at.
I wish the author would have noted how small a sliver of the "Western Left" resides in America. The mainstream political "Left" of America is "Western Center". Probably almost every single person reading this here on the 'ski knows that, but yeah, there are only about 100k members of the Democratic Socialists of America.
As someone close to or inside 'democratic socialist' on the ideological spectrum, but certainly not card carrying; Yoikes. The DSA press release has aged very poorly. The small numbers of self-proclaimed democratic socialists are very passionate about organizing to effect political change, but if the organizations react with entrenched, party-line groupthink, I'm not interested.
Criticizing NATO and the U.S. is fine, even patriotic, and we should never forget how stupid and tragic the U.S.'s middle east meddling was. But if you react in one way, and one way only, to evolving geopolitical power struggles, you don't deserve a platform. Learn2nuance.
This time, the establishment democrats got it right, more or less. That said, we would be wise not to let Cold War II minimize the domestic threat we're facing. Really, they're the same threat; autocratic oppression.
