Pretty much. I think it is a little bit of both, personally. Different types of alcohol do have different effects, but people are quick to make excuses for their behavior, and the type of alcohol they happened to be drinking is an easy escape goat. Someone has a bad night where they make a fool of them self, and they say it's because they drank tequila. I have a friend who only drinks whiskey, but says that he absolutely cannot drink Irish whiskey. He says even one shot of Jameson will make him feel all [expletive] up, like his body just won't accept it. I'm pretty sure he just doesn't like the taste, and the rest is psychosomatic. http://24.media.tumblr.com/tumblr_m2x4ahyPyE1r5zuiho1_250.gif
