Indeed. I see so many sayings along the lines of "fools speak, the wise are silent", and they are DEAD WRONG. That is how stupidity spreads. If we wise people speak out and put the stupid in their place every time they open their mouths, the stupid, eventually, will die out. Even if the one talking is too dumb to change their minds, our intelligent rebuttals may prevent someone else from falling for the idiot's delusions.
