The protests are docile. There are almost no reports of violence. I've seen more than one 'encampment' at various schools; it's just people hanging around tents. Most of the chaos and violence were introduced by law enforcement. How could the protestors be any less disruptive and still be protesting? Picket lines are more disruptive.
Protests with chaos and violence include large crowds destroying and looting. The reactionaries are so anxious to assume the protestors are awful that they just seem to assume or say there is 'chaos and violence' and people repeat it, despite overwhelming evidence to the contrary.
