Because it's a generic color descriptor ranging hundreds of light to medium skin tones across dozens of ethnicities

America screwed up race relations by using white for a grouping of nationalities (thus why italisns, Irish, and Spanish were non whites at one point)

And like another person said here, it's not a race. It's a genetic mutation. If white is a race then all Hispanics are bi racial, but the average stormfag wouldn't want to acknowledge for a second Hispanics are even half white.

Stop worrying about white, worry about nationalism and a preservation of American and Christian values, which are independent of any skin color or ethnicity.
