Yes, I recognise that you can still get drunk on wine, but when you compare the alcohol content of wines to the alcohol content of the drinks that came from distillation technology - you enter into a realm of drink that is used for the sole purpose of becoming very drunk (as a student often does) as opposed to a more social drunk more on the scale of tipsy. You don't see vodka at the dinner table.
Speak for yourself!
Of course, one could drink a lot of wine, or just a little bit of stronger drink, but I think the tendancy is still there from what I have observed. People (again I must admit I am generalising with students) often go out with the express intent of getting drunk. I think that is the kind of behaviour the church seeks to prevent with the word of wisdom.
Believe you me, people who go out with the express intention of getting drunk are not dissuaded if only wine or beer is available. You should have seen the university ski trip I went on where a vomit trough had to be dug in the snow to prepare for the beer relay.
In all seriousness, though, I think you may be misunderstanding how "spirits" (distilled alcohol) are generally used by those with an intention to get hammered. For the most part, they are mixed with juices, sodas, tonic water or some other liquid to bring the alcohol content down to a similar level as a glass of wine or a pint of beer. General rule: 1 glass of wine = 1 pint of beer = 1 vodka and tonic (or a shot).
Mixing is usually where the trouble ensues. For some obscure, unknown reason 1 glass of wine + 1 pint of beer + 1 vodka and tonic does
not equal 3 pints of beer, as any experienced drinker will tell you.
That is not to say alcohol cannot be enjoyed in moderation without consequence, just that perhaps the magnitude of possible consequences of irresponsibility with alcohol make it worth restricting those who would have no problem with it for the sake of those who would.
Well, I certainly disagree. I believe in freedom, and a big part of that is acknowledging the fundamental right of people like the students you know to learn for themselves what happens when you have three pints of lager and two shots of tequila and a couple cement mixers, and how it differs from what happens when you just have 7 shots of tequila or 7 pints of beer.
