The world is in greater peril from those who tolerate or encourage evil than from those who actually commit it.
(Albert Einstein, perhaps the most influential physicist of the 20th century)
What an insightful thought! We often respond strongly to those who do evil among us, applying the strongest punishment the law allows. But, is it possible that our toleration of those who promote evil, though not committing it, plays a more dangerous role?
Your eyes are too pure to look on evil; you cannot tolerate wrong. Why then do you tolerate the treacherous? Why are you silent while the wicked swallow up those more righteous than themselves? (Habakkuk 1:13)
