My religious beliefs aren't widely known, aren't very popular and are generally stigmatized by the media and popular culture in general. So, most people who would mock what I believe simply don't understand it in the first place and so what they say doesn't bug me any.

I'm also the type to keep it to myself, for plenty of reasons, and I tolerate other religions as long as they're not trying to butt into my life and as long as they stay out of politics (as what happens in the political area will, generally, affect my life if some idiotic law is created).

Even if someone were to openly mock my belief system, I wouldn't pay them much attention. Odds are, if they're rolling with mockery, they're just not intelligent enough to hold a civil discussion of the matter and, likely, haven't even looked up what it is.
