The Christmas decorations are not offensive to Muslims. If I was PM I would allow them. It's not about discrimination against non-Muslims, it's about insanely over the op political correctness from people who don't want to be sued to pieces because they accidentally offended somebody.
As somebody else said, you have had no experience of being a Muslim, and therfore cannot possibly know what it is like. Muslims commonly get stopped and detained at airports for no reason other than that they are Muslims, who are 'possible terrorists' in the eyes of the current leaders. Some Muslims are forced to change their names in order to get jobs. I've been spat at and had abuse shouted at me from across the street. Does this stuff often happen to white Christians? No, of course not.
No. When I said bad people, I meant people who commit crimes, but who are too powerful to be sorted out by police, such as leaders of nations. What I mean here is human rights abusers and opressors, such as Syria, Iran, Egypt, Lybia, USA, Israel, China, Russia etc. I don't like despots, whether they are 'Islamic' or not, whether they are Western or not. I also don't like neo-Nazis and racists, and if I was PM I would do everything possible to keep them from commiting their crimes.
