There will be no violence, unless they send out the BLM agitators and they do something stupid. It would be isolated if that happens not widespread imho.
There will be no race war. I'm not sure there very many blacks that are interested in a race war and neither are very many whites.
Most people if they are housed and fed aren't very dangerous.
There is an incredibly low amount of social trust between whites and blacks due to the non-stop agitprop propaganda coming out of the mass media. But in my day to day experience we (black and white) treat each other like it must be other blacks (or whites)
that are the ones causing problems. I've yet to have a black coworker, friend, acquaintance, neighbor or customer act weird or go into a BLM diatribe.
I realize I live in the suburbs outside of Chicago, not in Chicago. Yet, I'm reasonably confident that only a minority of the inner city blacks could be riled up for a BLM protest and that only a smattering out of them would be willing to take up arms against society.
The folks in the suburbs are heavily armed. Our police depts are heavily armed. All the blustering talk about race wars always has whites in a defensive position against roving and marauding inner city blacks. I just don't see that happening.
