Fine, I suppose I'm going to have to simplify this for you since you are CLEARLY trying to dodge the point of my post:
When the US was founded slavery was popular and legal. Therefore Black's must not have been evolved enough to be considered human when our country was founded BUT later they evolved and the majority started to detest it. Don't want to ruffle your precious feathers though so BEFORE they voted on it, and BEFORE the majority decided to change their opinions on the matter, THEN blacks weren't the same as whites. Does that follow your backwards logic close enough?
Admit it, your original reasoning was flawed. Trying to defend flawed logic isn't admirable, its asinine.
