I am surprised we haven’t seen some organized squads of decent people with *ahem” “non-lethal” *ahem* weapons just sort of storm the crowd and really go for a full confrontation with these snowflakes. The police wouldn’t arrest them, right?
Non-lethal, dress like they do, infiltrate and begin coordinated attack. This can be done in several areas. Make sure your groups are small, but able and ready, Attack and then leave. LOL!
