There seem to be a lot of rumors running around about reporting race on the form, scaring people into thinking they're going to be discriminated against if they report their race or some such nonsense. It's just basic demographic information every census has collected. If anything, it could be used to help fight racism, to show where political boundaries or school district boundaries have been drawn in a way that excludes certain races, or includes others. When you see district boundaries zig-zagging across a street and managing to put every white, Christian family into one district, and every brown-skinned or non-Christian family into another district, a census showing this can help make the argument that the boundaries are discriminatory (my boyfriend says this is the case in his hometown, for example...instead of drawing boundaries simply down the middle of a street, which would make an obvious district boundary, they've zig-zagged down the street to give certain ethnic, racial, or religious groups more power in an individual district, which is blatantly discriminatory).
