There is no election in sight, this is prime time to criticize the DNC. Anyone trying to shut down discussion right now is the biggest loser DNC shill you can imagine.
Depends on the critique. "Joe is a hypocrite for pardoning his son" is reasonable. "Joe proves that it's normal for politicians to act unethically, therefore criticisms of all unethical behavior are invalidated by the rule of whataboutism" is a transparent defense of Republican corruption.
My favorite postmortem take so far has been "why don't democrats get in line like republicans do??"
It's just such perfect mask-off liberalism, I just want to make a supercut of it for next election when libs are whining about why their unpopular candidate/policies aren't winning.
If you think your political role is to uncritically support whoever is chosen for you by the Democratic party, you are simply throwing away your political power. Worse, you are indicating that their strategy of shaming you into compliance works and they never have to provide you with any political program that aligns with your positions.
Instead of doing what the party tells you, think for yourself and work to build actual power for the people around you, not the capitalists picking your pocket.
