Because for over a century ago people with a funny color were slaved just because of that. We have gone a long way since the day the first slave was shipped from Africa into America. Now we have a African American president who will probally kill a majority of racism.
This is big for the destruction of races.
You know who sold the black slaves to us?
Black slave owners in Africa.
SLAVERY DOESN'T HAVE MUCH TO DO WITH RACE.
The fact that slaves were black is only signifigant in that it made it easy to say that they were different, and it was very obvious that they looked different, so there was no problem rationalizing that it was fine and making sure that people wouldn't get confused about who was and was not a slave.
They were black, so they weren't the same as everyone else, so they weren't people with the same feelings as us. It was okay to enslave them.
Also, if someone saw a slave walking down the street, they knew they were a slave because they were black.
No, they say all roads LEAD to Rome.
