You should hear what people say about people that were born and raised in the US South. Seems in some places, it's perfectly (socially) acceptable to pick on others, as long as you're picking on the 'right' group of folks.
Not trying to be aggressive, I just want to know why you think the cultural discrimination against white Southerners is equivalent to that against Chinese ethnic groups that are being actively oppressed, or some other group that is being actively oppressed.
