Be Vigilant
As the day approaches, remember that there are bad actors out there likely to try and blend into the crowds to sew dissent. DO NOT LET THEM.
We outnumber them, but we are poorly organized. This movement, sub, protest is an amazing first step (one that we should have done the moment the great orange buffoon threw his hat in the ring again). Make friends. Form local groups. We have this opportunity for change; let's not waste it!
They are scared. They are irrational. They are ignorant (willfully or otherwise). Many of them are just suckers caught up in something they're clueless about. Don't let them bring you down.
Some necessary paradoxes:
Do not be violent. Be ready to protect yourself.
Do not tolerate intolerance.
