Well it could but it would be most unpleasant. After living here in the Deep South for a while I am convinced that the blackamoors are still scared sh*tless of white men and white America in general. From some time spent in Texas it seems that a good size slice of the ‘Hispanic’ population simply want to blend into white bread America except maybe at dinner time. These people detest the ‘La Raza ‘ crooks, pimps, criminals and loafers and do refer to them as ‘beaners’ once you get to know them. So I think it would be a fight between traditional Americans and those of various ethnicities that want to be Americans and the rest. It would be nasty but perhaps not as hard as some think. Liberals today are almost abject physical cowards by definition, race type blacks can be slapped down by a those with guts, criminal and lazy Latinos can be dealt with and sent packing after some gunplay, the same for the ‘militant muzzies’ who are growing like cancers in a lot of places. It could be done if real Americans aren't concerned with being called bad names by the turd world and the UN and have enough guts to use some of the huge number of firearms they possess.
It’s hard to tell what the future holds, but it’s a shame it had to come to this.
