I refuse to be insulted by ranting citizens of such a cesspool of a nation. Having said that, seal the borders.
Foreign soccer matches seem to attract the worst of the worst, no matter what the country.
Some British fans make monkey noises and throw bananas at black players on the visiting team.
I don't know what it is about soccer that attracts that type of element. You don't see anything like it at MLS games, though.
BTW, how much complaining would there be if most of the illegals looked like Selma? None. So...where are they?
