Also, some people get, or claim to get, offended rather too easily in many cases, imo.

It's a sort of emotional blackmail. It's a method of controlling others. It often works. it's where there is no real feeling of offence; it's more a thought disguised in the terminology of feelings.

So I think any who are offended by BC and AD can, well, stay offended. Or they can use an alternative and see how they get on. I hope they get any pleasure at all from comedians, who make a living partially thru offending.
