It used to be that a slave counted as only 3/5ths of a person. No wait, make that 3/5ths of a white man, not just any old person but the gold standard from which all others are oppressed by.
You may think that the times of considering the value of one person as less human than another have gone away. You may think “sure, we still have problems with individual bigotry, but our laws treat people as, well people”
I am hear to tell ya- not a fucking chance.
