It appears the most effective tool against Nazi's and the KKK is a simple camera

[FLPanhandle]

These guys are being photographed and having their identities tracked down. Thus facing loss of jobs, ridicule from friends, family, neighbors, etc.

Instead of confronting these guys, bring cameras and let them know they will be outed.

I bet attendance drops for their rallies quickly.

1. And the camera is showing everyone what a bunch of cowards they are.

They are all being reduced to sniveling little cry babies. They march around all dressed up like their idea of Manly Men, but in reality they are nothing more than ignorant losers.

2. for now

with nazi president and justice dept at his disposal, don't be surprised if they start suing employers, schools for firings and even those who spread photographs and justice department will side with trump. They are branding nazi propaganda as politica speech and making a case that one cannot be fired for 'opposing' political views.

3. Shine a light on them...

...and the cockroaches scatter.

4. "I bet attendance drops for their rallies quickly." ... Or they start wearing hoods and masks.

5. Beat me to it

KKK style hoods and Guy Fawkes masks for the anarchists.
