I feel like you're asking people to believe these things simultaneously.

1. killing 180,000 people with political violence and counting is fine
2. Trump is evil and will kill everyone with political violence end democracy, elections etc.
3. Don't use political violence to stop this one guy though that's wrong.
4. losing based on rules and norms we want to uphold is the point even if it ends the rules and norms.

They are asking you to have mandatory operating assumptions that you can't even say out loud.

I don't think there's ever been a time where more voters have had to feel in their gut that the things that Democratic party says they want are completely incompatible all the actions they are willing to consider taking.
