I'll start. Turn Communist subversion tactics against them, and try the destabilize/crisis/normalize route on normies.

1. Destabilize their belief in the reliability of their information sources by showing irrefutable proof of media lies (e.g. full context of Trump "fine people" hoax).
2. Put them in crisis by holding up a mirror. Show them how in the last four years, the only ones fostering hate and inciting violence was them, and against a man (and his followers) who started no new wars, fostered peace in the middle east, and repeatedly called for non-violence. The potent emotional cudgel of the Nazi label beat the Marxist indoctrination into them- we will use it to beat it out, showing by their actions that they are the true Nazis.
3. Normalization. Extend an olive branch, and give them a path to redemption. Bonus: can try demoralization as well, if Biden's policies turn out to be terrible (which they probably will).
