You think people think like you. Most people don't. It's a popularity contest for most.
I think most people do. The people that don't just shout louder and happen to be in control of the legacy media and narrative.
I know very very few people (including among Democrats that I know) who would support most of this stuff but either are unaware beyond a surface level of what they are up to, or dismiss it as a much smaller thing than it actually is.
Sort of like if you pointed to a Nazi and said, that guy is a conservative Republican, you'd probably say, ok but he doesn't represent the party or their philosophy.
A lot of them don't support the radical left but think they're just the fringe that doesn't represent the majority of the party.
Most people are pretty centrist in my experience.
