This sort of thinking is stupid.
White Supremacists: Jewish people are 2% of the american population, but they hold the majority of top positions in the publishing industry. Do you oppose diminishing Jewish Supremacy? Are you saying it's okay?
Both of these arguments are terrible, and are both based on the premise that over-representation of some group in some industry or position constitutes a serious problem and probable conspiracy.
Ah, ok, so you don't think representation is an issue. Most people of color that have dealt with white gatekeepers will disagree with you. If you care to examine the part of you that holds that belief I'd suggest reading The Autobiography of Malcolm X, followed by some James Baldwin, Toni Morrison, Frantz Fanon, and bell hooks to start. Hate read it if you must, but give some experiences orthogonal to yours a chance.
I think you mean 77.7% white? It should be noted that the census counts North African and Middle Eastern as white, which is inaccurate. That number also drops to 62.6% when you take out Hispanics that describe themselves as white. So it's probably more like a 20 point difference than 2.
