Well, it's certainly a pity that Islamic terrorism is a big enough threat that they had to invent a Huffman-coded word for it. Though perhaps we can treat it as a relief that Christian terrorism is no longer so prevalent that we had to make a shorter term for it after we invented 'terrorist'.

Though I hear 'Crusader' is a close equivalent among many Muslims, for obvious reasons. I don't think Americans or most West. Europeans would understand that as a negative connotation though.
