Sure - but it's only offensive if they say it is. In effect, YOU can't find it offensive or declare it to be so unless YOU are offended.
Although I don't know why I'm posting that, because I happen to agree with you, which is partly why I also whinged about Dog's (very poor) jokes but anyway, that's my understanding of the "opposing" view.
Perhaps a proponent of that view might actually take up the cudgels, if I have it right, but now I must do some work.
