Being the average white Euroman type - a part of the majority race in America, I have never experienced racial discrimination.
However, I have been targeted as part of an interracial couple. Terrorized by rednecks in South Carolina once, insulted by my mother when she first learned of "my black woman." So, yeah, I had to go out of my way to experience racism. It ain't fun.
Brenda and I would get int ppls face tho. If either of us saw someone giving us a disapproving glance we would just say "kiss me." What a fun way to get back at bigots.
