Communities are overrun by illegal immigrants, the majority men, who don't respect Western culture or values. The locals are competing with them for housing and other resources. Is that racism?
If white folk commit crimes, they are asked to show their papers. Bank account, airline ticket, driver's license, rent car, hotel. Some states even require papers to vote. (not all)
I think stopping folks without probable cause is illegal in most states. Maybe 50 years ago. Can you post your sources? Of course not. You're just making sh*t up.
