Drinking is normalized in my entire country, but its still pretty obvious you're literally poisoning yourself with alcohol. That much I understood even as a teen.
I mean, some of abstinents who are strongly against alcohol sometimes do. As an attempt to make others stop drinking. And given that the drinking is normalized, they are small minority. I mean, they are small minority of abstinent too. Most abstinents are kind of content when no one is trying to force them to drink.
Drinking is normal in your culture —> drinking is not risky in your culture ?
This is patently false; drinking carries risks in any context, perhaps even moreso in environments which fail to recognize its potential for harm
It does not really matter how much risk it "objectively" puts you through. It attracts risk takers only if people consider it risky.
