That's why global perspectives are pointless. In THIS country and culture, no one has the right to not be offended. So long as nobody is inciting physical violence against anyone (certain protesters take note), or deliberately stating false facts to defame someone, then it should be fair game.
As for religious sensibilities, I couldn't give two hoots. Our ancestors weren't given much choice about abandoning their gods to become Christian and anyone who is too bothered about a lack of respect to other middle-eastern cults is in the wrong part of the world. What they want to do in the privacy of their own houses, or centres of worship, is up to them(within legal boundaries) but I don't see why the rest of us have to change our culture to make it more accommodating for them.
