They're the dregs. We've seen this
before.
The way to deal with these dipsh-ts, and with Republicans in general, is win elections and pass laws to shut them and their violence out of legitimate political participation. They're cowards so with 99% of them that's the last we'll hear of them. For the other 1% who are criminally insane, use law enforcement and the justice system to contain them.
We have hundreds of years of democracy and the rule of law created by the smartest and bravest people in our history. Those are the tools we need to face down the dumbest and most cowardly. Republicans are, underneath all the laughable bravado, losers. Treat them as such: if they want to mewl that the end of sexism and racism offends their superstitions, let them; it's a free country. The instant they take up arms to intimidate, our tolerance ends and they go to jail. One Oklahoma City was enough and these f-cks live in a world fantasizing even more heinous acts.
They've told us who they are.
Believe them and act accordingly.
