Can you give a realistic example of a black person using racism to discriminate against white people in the modern USA?
There's a store here in town which is in a predominantly black neighborhood. The owner of the store is black, and all of the employees are black. White folks who go in are never
greeted by the staff and always have to ask for help, while blacks are always
greeted by the employees and offered help. Black customers are offered help with their purchases (carrying out to the car, etc). Whites never are and, if they ask, their request falls on deaf ears.
So, yeah, there's an example. I have no doubt you'll completely dismiss it, but racism against whites exists in the modern world, and it's ignorant and naive to believe it doesn't...
Courage is knowing that something will hurt and doing it anyway. Stupidity is the same thing. That's why life is hard...
