Slavery...

So I'm watching the Color Purple, and I'm sitting here thinking to myself... what exactly was the POINT  of slavery? I watched the scene where Celie is in the supermarket and the preacher's wife is holding her daughter, the conversation passes and a (ofcourse racist) white man or store keeper scares the crap out of Celie to the point where she just runs out of the store. The white man looked puzzled and another on-looking white woman looked scared/disgusted. What was the point of her looking at her that way? She wasn't an alien, she wasn't some kind of demon, or bacterial disease walking the earth...she was a human being. So why did they even bring us here from a whole other country? Why because they were extremely insecure with THEMSELVES and disgustingly lazy that they decided to travel 50,000 miles across the country to Africa to find people to do their work for them? And on top of that do the most horrible, despicable and inhumanly disgusting things to another race... and then with a smile on their face call us "black monkeys" "niggers" and any other degrading name they could think of...this I ask was for what? To make yourself feel better? I came up with all of this because just seeing that extra in the movie (white lady shopper) look at Celie in that way as if she ASKED to darken your doorstep with her presence. Bitch! you brought her here so why look at her as if you never wanted her here in the first place...that's extremely backwards and stupid to me... But we're the dumb "black monkeys"....Hmmm.
