The Pilgrims came after 1600 years of Christian history.
As for the rest, Andrew (unlike you) knows basic history. Christianity was a religion that appealed strongly to slaves, and fact that Christian Europe did did not believe in bathing is a well-reported part of European history. If you continue to mistake simple fact for bashing, no wonder you don't know much history! (And you're unlikely to improve!)
The next time that Andrew launches into one of his rants, you'd be well-advised to ask what parts of it are speculation, and what parts are confirmed fact. It may save you some embarrassment.
