Well I know everyone has had their say on this but I need to have my say now.
Ok to start with I think the age should stay at 18, but this has no real reasons behind it other than I don't think changing it now is either fair or going to fix any problems.
The government is trying to use scare tactics to get this through. Namely the growth in teenage violence involving alcohol. Yet this rate was already rising as quick if not quicker before the age went up. Secondly of all the violent drunken murders in the past year I would like someone to name one case where the Attacker was 18 or 19...I did a bit of research and I couldn't find a single one. yes some 18 and 19 year olds have been killed when they were drunk, but none of them were the cause. So ok the ones who aren't doing the crimes are being punished.
And anyway stopping them drinking in pubs will only make it unsupervised and therefore probably worse for society...ridiculous, the changes are a lot harder to make than lifting the drinking age. This legislation is like blaming murders on guns. "Guns don't kill people, people do!!!" It seems to me that this law is just a response to a media hype.
Update to come later, but long enough for now.
