I would guess that for CM, "foreign looking" would mean anyone who would be unwelcome at a Klan meeting.
Not that I'd want to go, but I could get away with going to one of those. So could my brother, who was not born in the US.
Like I said, what's "foreign looking" Clayton? Could you look at me and tell me what percentage of my ancestry is German? Hungarian? Romanian? Who's the arbiter? What if my family came over a century earlier - is there something that happens over generations that removes that foreign look?
And just for fun, Clayton, I like to mess with people once in a while. While my normal speech is a pretty flat, boring midwestern accent, I sometimes imitate my relatives und shpeak mit der Cherman accent (either serious, Ludwig Von Drake style, or Peter Sellers) and can fool anyone that doesn't know me. If I do that in front of someone in authority, should I be tossed in the jug?
