Promoting destruction of property and intimidation has no place in civil society.
Such a high percentage of cars are SUVs that it wouldn't even be sending a coherent message.
They claim only to have damaged 40 cars one time. There's no evidence they did that, no public outcry in New York, and no corroborating evidence at all.
Again, there is no movement like this. There has not been a spike in vandalism against SUVs. I work with auto insurance data in my day job, and changes in damage to parked SUVs hasn't notably changed.
