Most American dysfunction is directly related to our "diversity" which speaks truth to the lie that it makes us stronger.
You have no right to an "all-white America." You are not special in any context but your own, personal achievements and the respect that you personally have earned from others.There is no basis for your assertion that "Most American dysfunction is directly related to our "diversity"." You, yourself, are contributing to what you call "American dysfunction."
I live in an extremely diverse community near D.C., with people from all nations, and there is no trouble other than what your own neighborhood might experience. We treat each other politely and with respect.
Just yesterday, I took the bus to do a whole bunch of errands. I first had to go to the metro station to get my pass validated (fluke in the metro pass procedure), and boarded the bus back north. The same bus driver (a black man with an African accent) who had driven me to the station was astonished to see me again and he automatically stopped where I usually get off. He called to me that this was my stop (he knew), and I had to tell him that I wanted to continue on the route to go shopping.
On the way back, the African-American driver and I began to chat about dumb drivers who give you "the finger" when they are the ones at fault and ignore yield signs. But I interrupted him when I saw, through the windshield, the yellow full moon that had just come up to encourage him to have a look. We were just two people enjoying the beauty of nature together. This is how we all get along. We don't march around with tiki torches chanting ridiculous slogans and we don't form "militia" gangs to run around in the woods playing soldier.
