That divides people though. They best things to stop this that I know of is a union of the people. If look back, there is always a point that I didn't know something or for some reason resisted learning it at that time for some reason. It could be anything, the person may have had a death in the family, distracting relationship, distracting tv (lol). So if I were to mock someone it would be just as if I'm mocking myself. I have all of those genetic traits too.
