Can we blame the crusades?
Gotta appreciate how the beheading Achmeds picked up on Zero's "misspeak", using the term crusades as they did their whacking.
I'm glad I have trademarked my "Phockobama@gmail.com" junk addy....
NO ! The Crusades were irrelevent then.
The Problem was "Islamic Conquest" by tribes in Africa who took slaves to sell
to ships captains for resale into the States.
That's like blaming the Cabbie for letting you get off at the wrong location in NYC .
Ignore the Islamic tribal wars, and blame the transporters and those who housed and clothed them for decades.
Then look for restitution generations after the fact .
