You're only focusing on the extremes variables there. 1-3 beers is very casual drinking and also doesn't mean that he is always have 3 beers every night like you bolded. Also when he refers to going to a bar it's only probably only a few nights a week like one or two. I don't know why you have such a negative view on drinking, but it's not as bad as you make it out to be. If you include the trips to the bar, he probably is averaging 3 beers a night, which is a bad idea if continued for a while. There are a million other things more people do on a daily basis that are worse for your health than three beers a night. It's only perceived as worse because you become intoxicated from drinking beer. How about the people that eat at McDonald's, drive without a seat belt, get extremely sunburned often, or play contact sports that cause brain damage? Those are just a few examples off the top of my head. Like I said, it's only perceived as more negative because it makes you drunk. He's not saying it's the worst possible thing he could be doing, he's just saying it's a bad thing. Just because he doesn't do "X" doesn't mean "Y" is justified. And it's not perceived as negative because it gets you drunk, it's perceived as negative because it puts you at a higher risk for liver cancer and all that [cabbage] excessive drinking does.
