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.
