Folks who were raised in Outerwhitelandia don't understand, or refuse to remember, that racial violence is as old as America itself. The deadliest civil disturbance in American history were the 1863 New York draft riots, when Irish immigrants ran around Manhattan lynching every black they could find, even burning down a black orphanage.
According to Thomas Sowell, the waves of Chinese in the 1800's probably suffered more than any racial group, much of the suffering instigated by Jack London who was a socialist union leader. The Chinese were not allowed jobs accept in a few industries (hence the Chinese laundry) and they died like flies. Nevertheless when Chinese gangs began to appear in California, Chinese leaders went to the police and asked them to lay on more with the billy-clubs and the gangs were defeated.
I'm well aware of that incident in 1863. I don't live, nor do I ever wish to live in such a place as that, either. I'm not sure what the point of your posting that in this situation was, but I take it that it must mean that since I choose to live in "Outer Whitelandia", I must be ignorant of all the enlightenment that there is all around me if only I would look. I might say that people in the places spoken of in the article are like animals but that would be an insult to all animals.
Do you really want the eloi to remember those days? You see part of the script given to us proles is that everyone who comes to the US becomes just like us and that is what we say because that is what is expected of us. You know those quaint little civil unrest periods called riots would last about a day if the proles remembered those days and decided to participate in their own gang fun.
