I'm right handed with a left eye dominance. I've shot rifles and shotguns from my left shoulder since I was a child. I've even fired belt fed machine guns from my left shoulder.
My view is that eye dominance isn't as simple as just right or left eye, but more of a sliding scale. At either end are people that have an eye so dominant that any attempt to use the other eye would be difficult to impossible. In the middle there are a few people who have no eye dominance.
People should do what makes them shoot the best, no the way other people think they should shoot.
