So as a left-hander you get a small bonus to your brain from being forced to use your right hand a lot and a right-hand design world. When you buy especially left-handed made things, you actually rob yourself of that advantage of gaining that ambidexterity. So I don't have a good hand and a bad hand. I have a fine dexterity hand in my left and a raw power hand in my right since that's traditionally what I've opened doors and other things with my whole life.
Whether or not I play a sport, with a certain hand varies by the activity
So in baseball I throw and catch left-handed
In ping pong and badminton and other racket sports, I can play either hand but generally I favor my right
When boxing or doing MMA I typically take a right-handed stance because I want my precision parrying hand out front and I want my raw power hand in back
For that reason I also shoot pool right-handed (left hand in front)
In volleyball, I hit left-handed
So yeah, generally I discourage my fellow Lefty brothers from doing a bunch of things to specifically accommodate themselves and instead embrace dual use that the righties will never have.
