Yea that word is used in many islamic or arabic influenced regions to designate non Muslims or colonizers. But many dont take offenceIn South Africa the worst racist term you could use for a black person is "Kaffir".. But anybody who knows the world well enough (or is Muslim) will know that this word is actually a term from Islam to describe a non-believer and has bugger all to do with ethnicity.
Pathetically it was brought down by dutch settlers who clearly didn't understand the term when they started using it for the local people here.
