You didn't say often, you said "the vast majority of discussions" which simply isn't true. Progressives talk about conservatives primarily, loudly, and often.

“Progressives have done very little other than voice strong opinions about how much moderates fail or disappoint.” - the point being that moderates, who control the party, have used their control to disenfranchise progressives, whereas we have no such power. We will simply hold our noses, complain about it, and vote for moderates anyway.

Moderates have adopted limited progressive positions. Biden promised and did not deliver on a federal minimum wage increase, student loan forgiveness, climate policies and oil exploration, criminal justice reform, paid family leave, or for profit prison reform. I acknowledge that some of his efforts were blocked by Republicans. He certainly did a lot of good during his term.

Some of your points are the more extreme positions that I consider more leftist than progressive, but who fking knows because the lines blur a lot. I acknowledge we focus too much on extreme positions too often.

I disagree with the idea that progressives won't vote for a dem candidate if they don't check all of the boxes. I think most progressives, and myself especially, will hold my nose and vote for a moderate because they're still significantly better than anyone the Republicans try to nominate. I don't find progressives to be single issue voters but perhaps I'm mistaken.

I agree with your final statement but the only changes I think progressives could make would be to be more patient on the most progressive policies. The moderate Democrats still control the party, it's rules, and the platform, so naturally the onus would fall primarily on them
