Urban actually called Muslims "infidels."

funny thing is (i may not be right) isn't "infedel" *gasp* ARABIC?!?!

[John Valentine]

Well, no not exactly Arabic. I think it is actually Latin based.

(in) meaning 'not' or 'un' as in 'inexpressible'

(fidel) meaning 'faithful' as in fidelity or even the name 'Fidel'

Put 'em toghther and you have infidel, someone who is 'not faithful' to the one true religion. Just a quick breakdown of the entomology (sp) of the word, if I am not mistaken.
