Indeed, I spent my yesterday afternoon re-reading of all things "Kingdom Come". A story about Super heroes and God. In the stories, good and evil are clear cut. Smite evil, cheer on good.
The real world, sadly, is not nearly as clear cut. But even if it was, it would avail me little as rarely do I ever have to face making tough choices. Mediocrity, as you describe it, surrounds us but does not seem worthy of the effort it takes to smite and so we live with it as part of our journey down the slippery slope that is life.
And so I content myself battling trivialities on-line, the closest thing I will probably get to fighting for truth, justice and the American way.
