I agree that it is a good idea to avoid groups of people making racial slurs. I was raised in Mississippi as a young lad. I left the state when I was ten and never looked back.
Do we rate riots like we do tropical storms? If so, this would be a tropical depression - probably a very appropriate term for this incident. The disturbance following the SF Giant's four game sweep (fires, property destruction) would be a tropical storm. Hurricane designation requires overturning and burning of vehicles.....
It would be wise to avoid any of these, whatever their cause
