外人 is the word most people seem to have a problem with, even some Japanese people themselves. 外国人 is the more "appropriate" term. I've never been really that bothered by either phrase, though, to be honest. It's not difficult to see why there is a blanket term for foreigners in Japan, because Japan is such a homogeneous country. I'd say it's more ignorant to toss around the word 'foreigner' in the US (and many parts of Europe) than it is in Japan.
