I too have watched Brass Eye, and they literally had MPs telling people about the dangers of "cake" in a previous episode. It showed that MPs and TV celebrities would literally say anything Anchorman style if it was put on a teleprompter / script in front of them. They are nothing other than paid actors.

While I don't believe everyone in Parliament is a moron. I think more than enough of them are moronic, out of touch, malicious or home combination of the three for it to be a problem.

Generally the only solution presented for any issue in the UK is banning something. There is no other course of action that they can envisage. So you end up in a false dichotomy, discussing whether something should be banned or not. There is no discussion why the issue is happening in the first place, only whether <thing> should be banned or not.
