As much as we may personally follow that dictum, we also become responsible indirectly - by giving alcohol to those we know will drive home, by allowing our children to go into the military, by putting out roach killer. Our whole society is based around getting the best crap and outdoing the Joneses down the street. No, what follows is that of realism and stark naked truth. The top of the Sins. It's too bad that stupidity isn't painful.
Ignorance is one thing, but our society thrives increasingly on stupidity.
It depends on people going along with whatever they are told. The media promotes a cultivated stupidity as a posture that is not only acceptable but laudable. Kinda like Al Gore saying he created the Internet. On equal footing with stupidity for what keeps the money in circulation these days. Everyone's made to feel like a big shot, whether they can come up with the goods or not.
