Be Careful of Tolerance

Endless toleration may reflect an indifference to truth; but when we oppose something, we equally expose ourselves for what we are and cherish.  There is little value in opposing things for no other reason than the love of fighting; but on the other hand to oppose nothing suggests we are blind, foolish, or careless.
