I did not take anything as a threat - What could you have done anyway, type in bold text?
The whole point of telling you to do so was just to illustrate the concept of all the rules being the same for everyone, including myself. If I had something that I held in high regard, capable of attributing the title of "holy" even, then I would expect it to come under fire. If I didn't have a sense of humor about it, then how would I ever survive in the real world.
And that's the problem that I have with the idea of removing all offensive images from the world. If something is so fragile in it's existence that it can't endure a little mockery, then what is it? How insecure are we when even cartoons make us feel threatened or offended? Satire and dissent are very very healthy things. If we close ourselves into a box where we only deal with things that make us feel pretty and happy and color our world with rainbows and bunny rabbits, then how are we ever going to grow. Doing so is the very epitome of resting on our laurels. It is being prodded and tested that drives progress within us, both personally and socially.
It's a damn cartoon. It's nothing more. It should not offend you, or anyone else any more than a picture of a rock being called a tree should be offensive. The basis of your religion lies in the words of a man on some paper, not in his corpse, or an image thereof.
