You're idea was that we're okay with the joke because its christian and that if it were muslim we would all be complaining about it. That we're sensitive to other religions but not christianity. you provide no basis for that believe and as there is no news post today about an album making fun of islam you can't really say that so I assumed that your source for this so called bias against christianity is fox news, as they tend to fabricating stories presuming such. You have no proof that this bias exists.
However just for the sake of argument let's assume that the bias does exist. Which would you prefer, that we all be okay with making fun of your religion or that you cant build your places of worship, or walk on an airplane, or even go outside without someone assuming your a terrorist thats about to blow them up. For the entire country to assume you are evil just because one douche bag claiming to be of your faith killed some people. Your choice man, prejudice in jokes or prejudice in life.
