Considering the long history of religions imposing their values on people we should be very concerned that a religion in the modern era that supports Sharia law, the abuse of women, honor killing, etc. is gaining significant influence and imposing its values in your western country.
The same would apply if a bunch of conservative Christian nuts tried to impose their values on my community. It is unacceptable.
It's not the same thing at all. This is, or at least was, a Christian country. Islam is an alien psuedo-religion. We don't have to apologize for favoring Christianity, in the same way we didn't have to apologize for favoring democracy over communism.
