Personally, I have seen much more offensive things going on here on a regular basis.
TheBansche, you did nothing wrong by posting that here. The domain is a little weird and probably worthless, but you could certainly do a lot worse (look at any drop list and you'll agree)
As for being offensive, this domain doesn't have nearly the same effect on me that, say, bestiality domains would, or even stupid trademark violations would. In fact, this domain falls squarely into freedom of speech/ freedom of religion domains that deserve to be fought for and protected from those who would try to censor them for political reasons.
While your apology is clearly sincere, I don't really think it was fully warranted, beyond maybe a statement that your intentions were not to offend.
Though I am not sure where you might find them, there are probably those who could find a use for your domain and make a thought-provoking site out of it. The nature of that site eludes me at the moment, but that's the beauty of the system we live under.
Best of luck.
