As with everything else in life, all is OK in moderation
So if i am not wrong you trying to tell that its not a big deal to drink in this modern culture.... But dont you feel that drinking causes a lot of problems...
He want to say it is bad if you drink big amounts. I think it is not bad to drink every weekend, but not some huge amounts, because it could be bad. It is same with food. You can eat some unhealty food, just if you don't eat it all the time, burgers for example.
