I Know many people who have different faiths ( not Islam) who willingly accept that America is a Christian country with Christian traditions . All they ask that in their private homes and meeting places they be free to give Ganesha a peanut. Thats perfect "multiculturalism" in my view.
C can mean conservative, it can mean Christian, it can mean confused, it can mean convoluted, it can mean conflated, it can mean curmudgeon. You must mean the latter. :)
