Servants of the devil

For a sufficiently long historical period to the left-handers was biased. And political preferences here played no role. And does it have a very wide geography.
For example, there are in English, the word sinister, came almost directly from Latin (sinistra). Initially, and the meaning was the same - left, left. But then yielded by the word has acquired a completely different color and in English this is of fundamental importance as "grim; dishonest. " There's heels with similar meanings, but essentially it does not change. Catholics lefty generally considered to be a servant of the devil. By the way, in Russian, too, the term "left" in many contexts has a negative connotation. With regards to the origin, method of solving the problem, but so much more. How retrained children in Soviet schools to write right! But the Arabs still left hand - for those cases that are below the belt.
To avoid the feeling that this influence of world religions - Christianity and Islam, we inform that the Japanese even thirty years ago, left-handedness wife could become quite legitimate reason for divorce. And the tribes of the Niger Basin women is strictly forbidden to cook of course, with his left hand.
And this genocide was formed right-handed against the background of what historically significant personalities among lefties was over - from the Great and Caesar to Osama bin Laden and Obama.
So why is this attitude towards people with "non-traditional" role of the hands and feet? Perhaps, after all - a purely human. Lefties much smaller. A homo, although he seems to be sapiens, but not like it when someone is very different. Annoying, you know.
