I've just spotted something hypocritcal about my response to Russell Brand.
With him, my feeling is live and live. Not my kind of humour, but if he makes other people laugh, so be it.
However, if this was Bernard Manning, I would be up on my high horse condemning and (no doubt) calling for him to be banned blah blah blah.
So I think it depends on what you think of the performer, rather than the specifics of what he or she has said in this particular instance.
If you don't like Russell Brand, you are unlikely to ever find him funny. I feel the same about Jimmy Carr, Bill Bailey and Chris Moyles...
