The Democrats aren't going to become the party you think you deserve. But they are the party we can use to achieve our goals. If we fail to leverage them effectively that's on us. Spreading this propaganda is self-defeating. It's an exercise in shooting yourself in the foot. The Democratic Party is what we have to move the needle to the left. If we insist on casting them in the most unfavorable light possible to everyone, we shouldn't be surprised when no one wants to vote for them and they lose. Your time would be better spent targeting the Republicans with this stuff considering they are the people who want to kill us.
Obviously the Democrats would do better if they adopted a populist message. We can't control the Democratic Party. But we can influence the rhetoric around how people view their vote. If we make the Democrats look like fascists who must be protested out of a moral duty, then we've done the Republicans a favor. If we point out the Democratic Party are a useful way to advance progressive and socialist causes over time then we've done leftists a favor. Let's do the latter.
Of course we'll see what happens next year with this. Seems like the party could die if it's leadership are all arrested. If it doesn't, let's use the Democrats to our advantage. edit: typo
