In my experience, alcohol just removes the chocks from things you wouldn't do sober.
If someone's secretly an asshole, they'll be an asshole while drunk.
I am as direct as a T-Rex with 'roid rage and about as subtle. It isn't intended to cause upset, I just prefer to talk plain. There are plenty of other people here who do the nice, polite thing much better than I can. I'm what you'd call a "problem dinner guest."
