Obviously I hope you're overstating this danger. My guess is that the MAGAts, however heavily armed they are, are mostly cowards. They will rant and rave on their "Truth Social" site, making grave threats against all of us "libtards" and "commies" but they will utterly lack the courage or organization to do anything other than stochastic terrorism here and there.
And the police, however sympathetic they might be to all this right wing rubbish, will generally have no tolerance at all for gun-toting MAGAt fanatics taking over the streets. It makes their jobs a lot more hazardous. And once they face real danger, these armed cowards will mostly scurry back to their computer screens and resume their hate-spattered doggerel.
