Oh yes alcohol is a drug, worse than a lot of the illicit ones, and I hate it just like the rest.
It wins me few friends to say this, but if i thought making drugs illegal (alcohol included) worked I'd be for it, I'd make it happen if I could. But after a certain point of examining the subject, I came to the conclusion that things actually seem to be more problematic when drugs are illegal than when they are legal. If you hate drugs, it's actually more in your interest to legalize them.
And this seems to be one of the things you always have a hard time with, Lark. You assume that if you take a moral stance, then the best thing to do is to legislate that stance as literally as possible. That's not realistic. Society and the role law has in it is very complicated. It's best to examine the likely consequences of a policy and select the one that gets the result you want, even if that means something counter-intuitive like legalizing drugs to make them less harmful.
Of course the other thing is that every problem actually ties into so many other problems that you usually have to make some kind of compromise. Everything has some cost, and some benefit, and you have to make the comparison and decide which benefits are worth the accompanying cost. I see a lack of this in regards to the so-called war in drugs. Cost-benefit analysis does not reflect on throwing pot smokers in jail very well.
Finally, Lark, you have had a problem of not providing your rationale for a lot of stances. What's confounding is that you seem to be less likely to provide rationale the more strongly you take a stance. So when it comes to drugs, or homosexuality, you can fight it forever, employing everything but an explanation of why you've taken the stance that you have. That isn't going to help anyone. Not you, and not the people you talk to.
