First of all, I think what you're asking about is racism in America, but there are white people, black people, and all other races in different areas that experience racism and discrimination in very different ways. For example, if you were to read about the current situation in Zimbabwe, you might find that a lot of white farmers living there have had their land seized by the government. There is also racism by people of color against each other. There is also discrimination among white people. So I think that is exactly what you said, that people mainly base their whole argument on personal anecdotes.
This issue became prevalent when affirmative action started.
It's basically when the majority are discriminated against because there is a quota for a minority to fill a job or position.
I do believe in reverse-discrimination when everything else is equal. Don't promote or hire to send to school the less qualified to fill the seats with whatever race. If I score X on an admissions test, and you score X on an admissions test, and you are the minority, the scholarship goes to you.
When laws are created to help one group of people which in turn hurts another group. So if a company or city is told to hire minorities, then white people for example are being reverse discriminated against.
This is one of the reasons anyway.
You can write as much as you want and try to make it look respectable, but it's been clear to anyone here: all your posts should come with the labels "racist, mysoginist, homophobic, religious freak".
