History has lessons for us now that Hillary and The Donald are the candidates. Unless you want Trump to be president STOP THE STREET DEMONSTRATIONS at his rallies. Street confrontation is just what Trump’s fear and aggression-fueled acolytes want. It allows them to play the victim and fight back at the same time. The optics so far (see California) have favored Trump.
And don’t participate in street demonstrations during the Democratic convention. I watched in 1968 when disruptions in Chicago weakened the Democrats and gave Nixon a path to victory. Work and lobby for what you want from the Democrats at all levels. Don’t try to destroy the only party strong enough to make #NeverTrump a reality.
DO attend Clinton rallies, and make lots of noise for her, carry signs and register voters. Street theater against Trump is fine: just don’t do it in proximity to large numbers of his supporters. Let the general public know how you feel. Your aim is to defeat The Donald, not pick a fight with his supporters.
