Clarify this to me if I'm wrong, but that's not what I can conclude by reading certain quotes of the Quran, which is basically the holy bible of islamism. http://www.thereligionofpeace.com/pa.../violence.aspx . Even if it is just a minority that goes out killing others, unless these other muslims have another bible I don't know of (and that'd be basically a different religion), you cannot deny that the religion supports violence.
And even if the religion isn't violent, in their culture women are subordinated, for example, and many other things I disagree with. I can't defend a religion that takes freedom away from people. If islam is generalized, we'd be going hundreds of years back in time.
It's alright that they want to live with this culture, I won't go to the other side of the world to make war on them, but please don't bring this to other countries.
And, 'discriminating' others should not be seen as a crime. What you can't do is attack other people for their beliefs/culture/whatever, you'll be infringing their rights by doing so. But if you don't want to provide a private service to someone for whatever reason, this should be your right. After all you should be the owner of your own life and of your private properties, and not a government's puppet that will be forced to do whatever they want you to do.
Discriminating people for their skin is irrational, I do not know any scientific studies that proves people tend to be more competent than others for their skin color.
However, denying yourself to do something to others based on their religion should be your right. For example, you have 10 appartments to sell, and you live close to them. You have people from X and Y religion making the same offer. You believe that people from Y religion will cause more harm than the X, and then you make your decision. Picking X is a discrimination, but it should be your right to do this decision whatever way you'd like.
