Islam is much more a race then just a religion, as it's more confined to a area then Christianity.
Though, if you said something against Christianity, such as they are mass murders (which is more accurate then saying that for Muslims), I would still of kicked it out of the thread. Radicalism is a thing in every religion, for example, Hitler's extermination of Jewish peoples was based upon Christianity, and radicalized. I don't see people saying, then or now, that Christians thus should not be let into countries, even though Christian radicals have caused far more damage then Muslim ones.
If you have a issue with me kicking it out, you're welcome to PM me. I don't usually handle content moderation as the systems op/admin but this was rather evident.
