No one likes xi. It is impossible to write, I mean which great mind thought it would be a good idea to turn a tornado into a letter, simply preposterous. With enough petitions, we can legally remove all "xi" found in the world. It will force all textbooks to utilise other variable or constant names and any manifestation of the letter after we achieve our goal will be made illegal, with punishments ranging up to the death penalty.

This is part of a bigger campaign, where one step at a time we will get rid of annoying letters to write, in order to build a world that isn't governed by chicken-scratch looking equations.
