When will people fight back? Just do it without permits. Have numerous video cams positioned and ready. FORCE them to come arrest people who are the epitome of peace.
Create visuals of the jackboots dragging Christians from the stream. These ain’t exactly lions in the Coliseum stuff here.
Hit em where it hurts. They are terrified about being cast as the Brownshirts they are. Humiliate them. Its a service to American Freedom, and therefore, a service to Jesus too.
If you don’t want to pull a permit, don’t use a national park.
