That's exactly what I find so unpleasant about the show: it's not right that Jeremy is given free rein to be as nasty and aggressive as he likes, and get applause for it too.
The guest was out of order, but he was basically mirroring Jeremy's own behaviour, (which had been carefully calculated to wind him up). When Jeremy walked forward menacingly and pushed his face towarRAB the guest, snarling, the guest did the exact same thing in response. None of it was acceptable...but Jeremy got applauded, while the guest got a couple of scary bouncers standing over him.
I caught a few minutes of this morning's show, and Jeremy was doing the same sort of thing again, trying to wind up a guest with an anger problem. All the usual tricks, calling him "Big man" and goading him "Getting angry now, are we?" It's repulsive to behold a grown man getting such a kick out of taunting someone who clearly has problems. Did anyone see how that one turned out?
It really does seem that the entire show is aimed to provoke and goad angry people into kicking off, so Jeremy can do his smug, smirky walking-around-arrogantly-behind-wall-of-bouncers thing that he seems to enjoy so much.
