Really?
I tend to think its a geography thing. Meaning, these smack down boys pull this stuff in locales where they feel safe and they can get away with.
Basically, they feel safe doing a knock down in say Ferguson but you never see it and never will in a small Texas town.
So, yes, one day, somewhere, they are going to trigger a backlash. Since law and order in parts of the country have broken down, not unlike post civil war lawlessness, the “backlash” may be unofficial and swift and overwhelming!
