aye-rabs can't stand black people, this is not a secret in other parts of the world, in fact it's pretty much common knowledge.
i don't feel like looking up the article, but when the war first started i was in college, and I stumbled upon an article where a captured taliban explained their racists views
he said that sometimes they would abandon a mission to attack U.S. soldiers if they DIDN'T see any black soldiers in that unit
he also said that it's particularly humiliating and insulting to have black soldiers occupying their land
the word for "dirt" and "black" is the same in their language too...
somebody is going to argue that I'm making this up, but look it up for yourselves and do your own research
