How illiberal can you get?

I see from today's papers that the LibDems are going to come out in favour of a ban on smoking in public places - even parks. William Ewart Gladstone must be turning in his grave. It makes you wonder what they think the word Liberal means. Personally I hate smoking - they say kissing a smoker's like licking an ashtray. Naturally I couldn't vouch one way or the other, of course... The bigger issue here is the Nanny State. We're constantly being told how to live our lives by people whose own lives are often pretty shambolic. I'd rather trust people to make their own informed decisions. Isn't that what a true Liberal should believe?
