How does that American experience for those children of Europe compared to slaves torn from their wives and children, facing a lifetime (not 7 years), of being treated as property threatened with death and subject to rape, forcibly separated from family because you are sold.

If you care about our black citizens, then go into their homes, live in their shoes in  Chicago, then come back and tell us your experience.  

I believe your intent is to help your black friends is sincere, but I don't think you've been in their shoes.
