Analysis of the social, cultural of France, who formed two together may not understand: the elite "and the middle classes. This allowed me to understand certain situations, such as large cities who vote left (+ bobos immigrants), for a left that I do not recognize and that I no longer vote. I feel strongly the move towards communitarianism, to a so-called multicultural France but live ensemvle and hopefully it will stop at the "live apart" without confrontation. Especially this author allows the reader to understand that too much immigration leads to confrontation and that there is no moral fault to demand a halt to immigration. This is a universal behavior.
