This is what a vibrant American community will increasingly look like. You simply cannot expect to maintain civilization by giving barbarians responsibility for upholding their share of the social fabric. As the social scientists have discovered, much to their chagrin, the more diverse a community becomes, the less contact people wish to have outside of their race and ethnicity. This is not hard to understand, given incidents like these. The problem is that European cultures tend to do nothing about obvious problems for far too long, then brutally overreact. The Western way of war is unlike the Eastern, it is total and destructive in nature rather than limited and predatory.
In other words, when the reaction finally comes, history suggests that it is going to be very ugly indeed. And the worst thing is that it will have been completely unnecessary.
