My point is some of the brightest thinkers have been "mouth breathers" and are so far removed from the idiotic meaning it stereotypically is supposed to portray. For some reason a lot of the time the really intelligent aren't genetically blessed to be the cool jocks, and are instead the freaks, geeks, and nerds. But they're also usually the ones who end up being the boss over the ones who were originally the cool jocks. Karma's a real bitch.
When you make fun of those for a physical defect, it causes negative karma that comes back to bite you in the ass, because those are negative thoughts. Those who become successes usually don't resort to that sort of petty thought, because it distracts you from the goals you're after from the drain it causes.
