Same in England. My sister visited last summer and couldn't wait to get out of London and its overwhelming number of Muslims.
Maybe that's Bush's secret plan: have the Mexicans shoot it out with the Islamics? /sarc
My sister goes to France every year to visit her in-laws. She is not only American, but of Jewish descent. Every year I get more and more concerned for her safety. Being the liberal she is, she used to scoff at my fears. Not after her last visit, even she was shaken by the muslim's growing open hostility. Her french is flawless and she is often mistaken for Belgium, an assumption she used to correct. She no longer corrects it.
