A big mistake that I believe takes place in the world at large, not just among Muslims, but even within the church, is not enough attention to the source of data on which conclusions are reached. This is especially a problem with regard to Christianity when people make judgments about it based on say the overall culture of a country which is believed to be majority Christian.
For example while in the USA probably 80% of the population self-identifies as Christian, a far smaller percentage actually is active in practicing their faith. This means that Christian influence on the culture is not the dominate force that it may be perceived to be. And so what is culturally acceptable is often mistakenly considered condoned by Christianity, when in fact we who take our faith seriously are actually opposed to it. Yet, and here is the hypocricsy which I suppose all human beings from time to time fall into, though on the one hand opposed to that which pervades our culture we are not immune to it, may sin, and still be guilty of it as well.
Ok but there is a problem with many christian groups who even bless same sex couples, because "Jesus loves all". On anti or pro homo -marriages marches, pastors are on both sides of barricade.
