Being a badass is overrated. Badasses don't have moral integrity, they don't care about anything but themselves, and they don't take responsibility for their actions. That's a form of cowardice, IMO. To quote the very non-badass Morrissey: "It's so easy to laugh, it's so easy to hate, it takes guts to be gentle & kind."
I voted INTPs as the least badass, but I don't mean it as an insult....not totally anyway. They just seem too detached from the real world to do any of that action-y stuff badasses do (:cough:nerds:cough: ). FJs seem pretty non-badass also, but mainly because they care, and caring is good. Martin Luther King Jr. pictured above is not badass in the slightest.
