Something isn't offensive unless it's intended to offend.

Well, there is passing wind in public...

The point about whether things are rightly objected to as offensive, and that is whether they actually do cause reasonable offence. So, in this case and similar (Chrisrmas celebrations etc), "Do the traditional terms or practices actually cause offence to religious minorities?" - and generally the answer is, they do not. The objections tend to come from people who are not in reality offended but have an agenda of their own.
