Let's see ... what do I do when people mock or criticize my religion?

Usually?

I laugh.

Because the vast majority of people criticizing my religion have absolutely no understanding of it. Of course, some do -- but those are the more civil, "this is why I disagree with you, and this is what I believe instead" ones. The "you're stupid and wrong and I'm right and you're stupid" ones are a special combination of ignorant and arrogant. Some may try quoting the religious texts of the religion they're attempting to argue against, but (much) more often than not, they either misquote, quote out of context, misinterpret, or completely manipulate the passage they attempt to present.

The last point, we have seen in this thread.
