People are entitled to mock other people's beliefs if they so please, I generally try not to, because unless it actually harms another living thing it's no skin off my nose what you believe, but nor should it be to you what I believe, and that is where religion or more usually Christianity has issues. You all always try to convert and ram things down people's throats, because that is the nature of your religion to ' spread the good news'.you can't be offended when people consider your wonderful truth as slightly ridiculous and therefore take the mick out of it.
'It's now very common to hear people say, "I'm rather offended by that", as if that gives them certain rights. It's no more than a whine. It has no meaning, it has no purpose, it has no reason to be respected as a phrase. "I'm offended by that." Well, so flump ing what?' —Stephen Fry
