>Do I support people's right to protest? Yes, but... You can't honk all night Block major infrastructure for days Desecrate war monuments Flood 911 with fake calls

I suspect how much people support "people's right to protest" is directly proportional to how much they support The Cause. If they don't support The Cause, they want protesters to be as out of the way as possible (ie. "free speech zones"). If they do support The Cause, anything up to and including violence/vandalism is justified, because a few causalities would be canceled out by all the positive effects that The Cause would bring.
