What's one of the biggest problems in our society today? Easy, too many people that are full of shit. That alone is not the problem, the problem lies in the fact that not enough of us will tell someone just how full of shit they are. This lack of action is what creates assholes.
So next time someone is spouting off like a total idiot, don't just let it go or walk away. Stop and tell them in detail just what kind of fucktard they are. It's the only chance we've got. And if they really won't listen, I've found that five knuckles to the chops works damn well. Now get out there and do your part!
