You are raising an important point. If protests are too “family friendly” you end up with more of a public festival and the state knowing everyone will go home without issues and doesn’t have to take the protest seriously.

Protests need to be large and they need to have aspects for every level of activity and escalation-readiness. If they are only “family friendly” then nothing will come out of it. If they are only “black block” they will lack the mass necessary.
