Left-handers (or, as we prefer to style ourselves, the “differently handed”) are clearly an oppressed minority. Kevin Drum, typically, tries to explain the problem away by paying attention to the numbers. But the linguistic evidence is overwhelming: “sinister,” “gauche,” “cack-handed,” “a left-handed compliment,” “left behind,” versus “dexterous,” “righteous,” “right-thinking,” “human rights,” “the right stuff,” and so on. Only in politics is “left” the name of the obviously more virtuous position.
Naturally, the default state of all equipment (scissors, for example) is dexter; left-handed equipment is less available and more expensive.
In some cultures, the social pressure for chiral conformity is overwhelming. Cultures where food is taken by hand from a common pot are especially rough on the lefties, but they’re not alone. Reportedly (i.e., according to a rumor I once heard) Japan has no left-handed people, though it has a large number of very, very clumsy right-handed people. [Of course, some of us are ambisinistrous: that is, we’re equally clumsy with both hands. But that’s another story for another day.]
Since every oppressed minority needs a liberation group, and since every liberation group needs a sign and a slogan, I urge all my fellow sinistrals to raise their left hands in the air, fists clenched, and shout “Left on!”
