I just flat-out don't believe that radical Muslims, which is only a small portion of all Muslims, which are a tiny fraction of the population, have a chance in hell of producing a significant change in Britain, or the U.S., or Canada, the invertebrate nature of your average USBritCan liberal notwithstanding.
The bigotry of a portion of the white male Christian population, however, was once the law of the land, and given that a sitting United States Senator (Rand Paul) has called for the repeal of the Civil Rights Acts, I consider that bigotry more important and dangerous than the bigotry of a fraction of one percent of the population.
