But really, with 650 MPs there's bound to be a few that are a bit silly at least some of the time. You can hear some wild takes at the local pub too (or nextdoor), but that doesn't mean everyone in your area is a moron.
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.
