Not surprised, Democrats have changed completely just in my lifetime, almost doing a 180 in many respects. The party that was once completely anti-racism, anti-war, pro working class, pro free speech, free love, etc. has mutated into this fear mongering, xenophobic (Russia), identity politic obsessed, divisive, pro-censorship, puritanical, and hateful group of people just in the last 15 or so years. I know I'm generalizing but those are the people that dominate the political conversation within the party at least.
Kucinich is about the last one I somewhat respect.
And that Kids is what we called progression. Its hardly the democrats who changed into that its the bigger part of people in their 20's and 30's in western society who decided this is the way forward. The democrats and other political parties just cathered to this idea of progression, luckily it mostly backfired for now.
Please excuse my (probally) poor grammar
