If you were a person of color than..you wouldnt get one to pitch. You would have been property. Your owner would get it and fill in which would include you.
I wasn't referring to back in 1810, I meant today. If I were a person of color today, and were planning to answer those questions asked since the first census, I'd be legally in my right to pitch the census form because it wouldn't pertain to me. I wouldn't be white, and I wouldn't be a slave (well, except to the Federal Government, perhaps...).
