Southpaws, lefties, sinistrals. All these terms describe a misunderstood group of people: left-handers. Lefties have been unfairly treated for hundreds of years.
Enmity against left-handers is thought to have begun with ancient sun worship. Most of these sun worshippers lived in the Northern Hemisphere and faced south when worshipping the sun. Under these conditions, the sun appears to move from left to right. Since the sun moved toward the right, ancient peoples saw everything related to the right "good" and everything having to do with the left as "bad."
The Bible contains about 25 unfavorable references to the left hand. In the best known example, in the Gospel of Matthew, Jesus says: "When the Son of man shall come in his glory, and all the holy angels with him, then shall he sit upon the throne of his glory: and before him shall be gathered all nations: And he shall separate them one from another, as a shepherd divideth his sheep from the goats: And he shall set the sheep on his right hand, but the goats on the left. Then shall the King say unto them on his right hand, 'Come, ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world.' ... Then shall he say also unto them on the left hand, 'Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels.'" (Matthew 25:31-34, 41)
The custom of shaking hands comes from medieval times. When two people met, they would hold each other's right hand. As weapons were usually carried in the right hand, this would show that neither of them was carrying a weapon. Lefties could not be trusted because they could shake their enemy's right hand and hold a sword behind them with their left hand.
This enmity toward lefties can be seen in many languages. For example, in Latin, the word for "left" is sinister, which has come into English meaning "evil." The French word for "left" is gauche, which in English means "awkward" or "tactless." The English word left comes from the Old English left, meaning "weak."
Nowadays, most societies, religions, and cultures no longer scorn left-handedness like they used to. It's something you should take pride in. I am left-handed (why else would I be writing this page?), and though it can be difficult, I like it. You and I are part of an elite 10 percent of the population, along with the ranks of Lewis Carroll, Nelson Rockefeller, Julius Caesar, Charlie Chaplin, H.G. Wells, Paul McCartney, Babe Ruth, 7 U.S. Presidents, and others.
It's important to note here that no one is exactly sure how many lefties there are. Estimates range from 2% to 30%, but 10-12% is the most likely range. That puts the number at about 630 million to 750 million lefties worldwide.
