I'm sorry, since when did alcohol become a problem?
Isn't the real problem the responsibility of those people who choose to partake, and fuck it up?
If you're trying to use some kind of reverse psychology to illustrate that alcohol, while legal, isn't any worse than other 'Class B' drugs (I'm assuming pot is the issue), then why don't you just come right out and say it? I don't think this, if that's your intent, is any better of a tactical solution.
If you'd like to argue the merits of legalization of other class B drugs, then start a topic with that name.
If you think alcohol is really something evil and needs to be prohibited, then you need to have a beer and relax.
