I suppose that there exists a rational answer to the above question, but I do not know it. The word "football" used to be the name of the game played with *foot* and *ball*; the "American football" is played in a slightly different way. It is important to clarify the issue about "football", because to improve the world, we should first learn what the words actually mean. If we solve the question of "football", we could gradually make clear what "democracy", "freedom", "human rights" and similar things actually mean.
