Now I don't really want to enter into a debate here, but I really would like to clarify a few of your points:
This is true. However, Jefferson was quite conflicted on the issue of slavery. In fact, many even call him a hypocrite because not only was a he a slave owner, but it is also widely believed now that he had an affair with one of his slaves, Sally Hemmings. Besides all of this, upon his death, Jefferson's will revealed that only a select few of his slaves were to become free.
I have a high respect for Jefferson as a leader and thinker, but I do have to doubt some of his principles in regards to slavery. It's not as cut and dry as many people think it is. Jefferson himself once said "It seems we now have the wolf by the ears, and we can neither safely hold on nor let go."
This is an example of micro-evolution, not macro-evolution. I think everyone in the world should [hopefully] believe in micro-evolution. THe difference is this: micro-evolution is the change of an organism within its species, whereas macro-evolution crosses the boundaries between one species and another. For example, miniature horses have been bred for thousands of years, and with careful breeding, they have managed to "evolve" into smaller and smaller animals. However, trying to breed a cow and a horse would be rather complicated.
