You say that christians are rejected because of their faith while muslims are not. I do not believe this to be the case. I think people support the freedom to be muslim, just like people support others' rights to be christian, jewish, buddhist or any other faith. I am an atheist and I have several christian friends and many of them are great people, but the fact remains that we have underlying differences in our beliefs, and that will always act as a sort of wall between us. I fully support peoples' right to follow whichever faith they choose, but certain religions, as I see it, promote ignorance. Don't get me wrong, some aspects of religion are great. However, the fact remains that Christianity, and other religions, have a different view on many issues, such as same sex marriage and even evolution than I do, and this huge difference of opinion on matters close to heart will no matter what drive a wedge between religious and non-religious people. This goes for christians as well as muslims.
So I don't think people are more or less accepting og Islam than Christianity, I think people simply aim to protect the freedom to be muslim. What you view as acceptance, I view as an attempt to safeguard a democratic right that is threatened in today's political climate.
