This is a “given”. It has been for quite a while. Any sane person not of a mind to become or stay an urban denizen should have realized this long ago.
If you live in or near an area that is served by mass transit, rail, or bus lines, you are going to eventually be in danger from the infestations of urban cities controlled by Democrats or minorities.
That won’t change. The prudent thing to do for those inclined is to move out into this vast country where those conditions don’t exist. From my perspective, I really could give a crap happens in these places.
Also, it’s a lie from hell that whites want to, metaphorically or otherwise, slap a black person upside the head. For me and the whites I know and love, all we want is to stay the heck away from them. If it harms them that we want to stay away from them, then something is wrong with them, not us.
The rail, mass transit or bus lines will become dysfunctional during mass urban riots.
