Well I don't want to get in a pissing contest with you since it's pretty obvious you are not interested in any sort of meaningful debate.
But if a russian appeared at my establishment, who wasn't drunk and looked like he had a job and was generally trying to get by in life like the rest of us I would be a pretty petty person to refuse him service based on my experiences with his drunk countryman.
Because one drunk russian showed up at my place I ban the entire people group? How does that reasoning work?
You're a biggot, but at least you don't try to hide it. What worse then that, though, is if you're American you're more of an Uncle Tom then an everyday Mississippi biggot.
