Ignorance may ultimately be the reason for the downfall of American society. And in the opinion of some, tolerance breeds ignorance. The recent incident in Dearborn, Michigan where Christians were arrested for handing out religious literature outside of an Islamic festival, is part of a much larger issue than the rights of people handing out pamphlets on public property. It is about destroying your enemy from within.
"A man can no more diminish God's glory by refusing to worship Him than a lunatic can put out the sun by scribbling the word 'darkness' on the wall of his cell" C.S. Lewis
