OK, that's just like, your opinion, man. It's a common argument because it's a good argument. It absolutely adds something to the discussion, because it shows how our acceptance of alcohol is just a fluke of chemistry. Did I not explain why it was a huge part of society? It's easy to make, every human society has access to it, it's fun, and it allows you to be social. Other drugs are fun and let you be social too, they just haven't been as accessible as alcohol. It is ignorant and hypocritical to celebrate alcohol consumption while frowning upon the recreational use of other, safer drugs like marijuana. I can't figure what the point is you're trying to make here. Maybe you want to rewrite it?it ignores the reasons that alcohol is a huge part of society.
Starting from a point of "This is how things are" allows you to explain why that shouldn't be the case instead of the equivalent of pointing at a kid in the cafeteria and whining that he has two ice creams and you don't have any.
I think the problem is that he wasn't necessarily defending it because of its traditional value. I think what he was trying to get across is that it is a relevant part of the issue, and one that was completely ignored by the article. I don't think it was pro-alcohol or anything, but a criticism of the argument itself. That was just my interpretation of the argument though, i don't want to be putting words in the tacocat's mouth.
You basically just compared buying a beer to slavery. You are part of the reason I don't talk about drugs on the Internet. I'm glad you're clever enough to find a rhetoric flaw with a statement by someone who probably agrees with you but I will continue to dread an orange hubwheel today.
