Perhaps the most blatant discrimination in society, and one about which we hear no objections, is that which is against left-handed people. The way we write the English language is against them. The natural motion is to pull the pen as we write, but left-handed people have to push it (which is more awkward), or curl their hand around so that they pull the pen from the other side. The pressure required to use scissors is different for the left hand. True, they do manufacture left-handed scissors, but if a person picks up a pair that is handy, it is almost always going to be one that he will have to use with his "off" hand.
Why is there no outraged social movement demanding an end to this unjust discrimination against left-handed people?! Hmmmm?
