modeller - i have to speak up in doctordb's response here.
I entirely agree that there have been instances when AB'ers have been pulled up for unsavoury posts, only to whip out the 'I have a sense of humour - you don't ... card', but I do not believe that this is the case here.
doctordb's post was ironic, although in common with a few others, I did not find that immediately apparent.
However, given that we can now accept that it was posted with a sense of irony (and the uses of the concept are tricky, as I advised in my response) -in my view, it is not fair to shoot him down for deliberate offence.
So yes, there are indeed instances where people accuse people of a lack of humour for not being amused by their offensive rhetoric - but this is not one of them.
