I think that alcohol certainly loosens inhibitions (much needed loosening for some) ... causing us to act as more extreme versions of ourselves.
Drunk positive: Maybe the guy you make out with is some one you've "had your eye on" but needed some liquid courage to approach.
Drunk negative: Maybe when you're out drinking you're more "affectionate" with strangers because you secretly crave attention and validation. Same for being loud and obnoxious. If you're in a relationship and spreading the love with others when drunk, that probably means you're not a happy bunny when sober. I think infidelity is a symptom of a bigger problem. But that is a blog for a different day.
When you get drunk you forfeit a lot of self control. If you're angry about something, you might take it out on the wrong people. In that respect, I do think people say or do things they don't mean, so if you really care about the drunk offending you ... cut a little slack. They are missing their mouth filter and a lucid mind to know better.
Am I excusing unruly drunken behavior? Not exactly, but there should be room for forgiveness. And lets be honest, some people are just more fun when drunk. Or maybe they're more fun when I'm drunk ...
Anyway, we all know that if we intake too many spirits we'll act like idiots, true – but should everyone then quit the drink and stay in to play bingo? I say hell no.
Chances are if you're all up tight about the silly inebriated monkeys around you, you just need another drink.
(Unless you're the driver, in which case you are doing a great service for your friends. Still, though, lighten up, negative Nancy, and try to pull the long straw next time.)
