Civitas bills its blog as 'Classical liberal comment' and indeed old JS Mill features largely in a recent post looking at binge drinking.
As I've mentioned here before, the libertarian freedoms that old JS advocated were curtailed for those under 21, and in similar vein the Civitas blog poses the question whether raising the drinking age to 21 would curb bingeing.
I don't recall being markedly more mature at 21 than I was at 18. It's always seemed to me to be illiberal indeed to allow a man to marry and be killed in battle but not to enjoy a beer before either event. But then I'm an Old Tory not a Classical Liberal, so would approach binge drinking from another very different direction.
Unlike Liberals, Tories feel little reservation in applying societal standards of morality. I'd shame and humiliate the binge drunks; posters of a comatose wide-boy laying in a pool of his own urine, posted in his local community with the question 'Would you date this man?', or posters of a pantie-less lass spreadeagled on the pavement in a puddle of her own vomit with the question 'Would you take her home to meet Mum?'. Combined with more arrests and convictions for Drunk & Disorderly - let's get the plods off their arses doing something useful for once - a strong dose of public moral hypocrisy is the one way to make inroads into binge drinking.
I admit hypocrisy unashamedly; I've drunk alcohol on a heroic scale all my adult life, and with very few exceptions long ago have always behaved impeccably in public whatever industrial quantities of booze I have taken. It's a combination of being able to take it, and knowing the limits. You see, the problem isn't alcohol - it's self-respect.
