How thrilled would you be if I threw a traffic cone on or snowball at your car or house every day? Is that response unjustified because my actions are unlikely to cause damage every time?

The line between peaceful protest and rioting is property damage. This looks intended to be peaceful, but the intent is ambiguous. All it takes is a toss too hard or a hooligan to cross that line, and the line is crossed and civic argument toasted.

Put another way, this is aimless catharsis. Not civic engagement. It’s about as mature as the folks who were egging Google busses a decade ago, and now decry the budget cuts those jobs leaving San Francisco bring.
