It doesn't matter because my argument is theoretically irrefutable (obviously meaning it's practically irrefutable as well).
Your theory is irrefutable under the assumptions that you have made. Theory is only right in practice if your assumptions are correct, none of which you have proven to be true or have even given empirical evidence, other than state that people are generally right-hand dominant, which doesn't necessarily imply that one-handed cubing is an activity that relies on the dominant hand. Think about when you type on a keyboard, do you think your right hand is doing a better job of hitting keys than your left hand? Flicking a cube is not a particularly more taxing task on your hand than hitting a key, and like typing on a keyboard quickly, techniques for being quick at one-handed solving have to be learned on either hand (or both hands in the case of the keyboard).
In the case of either right or left hand, to maneuver a cube with one hand, you have to teach yourself how to manipulate the cube with one hand. It doesn't come naturally for either hand -- you have to learn pinky flicks, flicking with the back of your fingers, how to grip the cube, etc. Since you have to teach yourself these specific things, it's very plausible to think that the learning curve on either hand is the same or at least comparable, so why not take advantage of the large base of knowledge you already have from two-handed solving? Having been a righty OH solver who converted to lefty, I don't think the learning curve in terms of dexterity is any different for either of my hands. (yay sample size of 1)
I'm not saying that I'm right or wrong with my examples here, but you are making broad generalizing claims that go against the experiences of cubers who have tried OH with both hands and have developed resources based on the things they have learned and tried, and appear to have little experience in this yourself.
Also, thanks for bumping an old topic for the purposes of starting a flame war. You should probably drop the rude, flame-bait language here if you want to have a civil discussion and not face infractions.
