I'm brand new to this site, but I think I'm going to like your contributions.
I haven't read the whole thread yet, but I've noticed you touch on two issues: 1.) Progressives settle for a Democratic party that doesn't embrace them. 2.) All good people need to support the Democrats this year because the Republicans cannot address racial reality.
I agree with you on both points. If the Democratic party is supposed to be the more liberal of them, then it needs to start addressing progressives and millennials. It's an old legacy party that operates decades in the past at all times.
Racism never went anywhere. It was pushed into the closet for a long time. The age of Trump welcomed racists out of their closets and into mainstream American culture again. There can be no equivocation for supporting people and a party that sanctions, adopts, and encourages racism. I resist ever viewing political matters as good versus evil, but in 2020, there can be no doubt. No good person can support Trump and what he stands for; and every person who supports Trump and what he stands for is not a good person.
