I'm not sure I buy that certain liquors make people react differently than others. 80 proof is 80 proof. People let a bad night or three make them think that some liquors have special properties. I highly doubt that anything besides the amount of alcohol consumed had anything to do with how anyone behaved.
Also, tequila ain't got shit on single malt scotch whisky.
I went overboard with tequila at a bbq labor day weekend. I had been drinking all day and then took who knows how many shots of it. I went home at 10:30 that night and puked my guts out. So...fuck tequila. Only whiskey and beer for me.
