Let's look at the facts here. Slaves were expensive. Do you think the slaveowners would torture or try to kill expensive investments? We bought slaves from African tribes. Let's blame them, too. They slaughtered each other and took slaves, and we bought slaves with rum and guns. The slaves went to the caribbean mostly, then to america. Slaves were hardly beaten, except for a few extreme cases (would you almost kill a very expensive investment?) Slave codes were tame-capture and return runaway slaves. In barbados, slaves would be burnt, killed, tortured, and have hands / feet chopped off for running away.
Some slaves were content enough to continue working for their masters after the civil war. Some slaves were set free upon the master's death, and offspring between the master and a black woman were set free.
Segregation was not an american-only thing, was exhibited in several places, and wasnot only against blacks. (even blacks hated other blacks from different tribes in africa) Immigrants especially hated blacks, as slaves dominated the labor markt in the south, restricting jobs to the north, and after the civil war more blacks were taking "immigrant jobs," which caused more strife between the two groups.
I'll wrap this up before it's a full blown lecture- Americans were not the only ones who had slaves; we treated them better than other countries, and it was not only whites who hated blacks. The mainsource of slavery was african tribes themselves.

Everyone should just shut the heck up and stop yapping on and on about what they know minimal background information on. Learn some real history.

Snow is racist. It does not have an equal amount of colored snow as it does white snow. We must find a way to alter nature so that snow becomes colored.

When you decorate your tree for Christmas, you must put at least 24.8% colored bulbs, and they must be placed throughout the tree and not segregated in any matter.
