There comes a time in someone's life when it's time to admit that the whole point of assigning a label is so that [whatever it is] which is assigned said label fits under it and all things that fall outside it are ancillary to said label. Also, please don't follow the Wikipedia link motif. It's extremely trite. If you have a point to make, please use your own words. As you start typing, you may even get a chance to re-examine your own thoughts (I always do).
