A tart temper never mellows with age; and a sharp tongue is the only edged tool that grows keener with constant use.
Washington Irving, 1783-1859, American Author
When we give into the urge to use our voice in hurtful ways it is childish; everything we think is not just, some of it should never be said. People without a filter on their thoughts spew them everywhere and feel justified in doing so. Invading someone else's space and punching them in the chest is a criminal act, using your voice to do the same thing is more hurtful and the effects are often life long, yet that is not considered a crime.
Temper is a negative reaction that can be harnessed for good. Getting angry is often justified, using it to fuel your determination is healthy, but bitch slapping with a temperamental person is pointless. You cannot change a mind that is convinced it is never wrong, wasting time trying is a fools errand.
A sharp mind is a great thing. But a sharp tongue is a loose cannon that never stops firing at everything within range. Being the loudest, or rudest, or meanest does not make you the rightist. It makes you an outcast if used often enough. Seems a much better thing to sharpen your mind than your tongue. Better to draw people with knowledge than repel them with spew. The choice is simple.
