I'm not going to get into a diatribe about it, but playing dumb about what the motives were behind each of the France attacks and who did them, and what cultural background they identify with won't keep you safe. You can buy into the illusion of the self-interested immigration industry and its political propagandists, or you can use common sense and realize that the success of multiculturalism relies solely on the people selected to get into a given country. That selection is not based on race, but on whose cultural background is most likely in recent history predisposed to commit terrorist acts in the name of religious fanaticism. If you think that's being paranoid, or you choose to project racism into it, try to envision yourself as one of the gored victims on Boulevard des Anglais in Nice today, many of whom likely thought an open-door immigration policy was a good idea, and anyone who disagreed was a racist. Sorry to say, but the fox is among the chickens now and it's too late to go back in France.
