I'm going to agree with Mytefe on this one.
The joke is definitely targeted at a specific social group (Irish) and is seems to be targeted at a specific sexual group as well (homophobes and/or homosexuals, whichever). If it had only been one or the other the joke might have passed unnoticed (as have a few of Cave's other jokes). But the combination made the joke more offensive, at least to me.
