Probably about 80% ambidextrous -- right is probably my favoured and most precise but I can rapid chop a carrot or dice an onion with my left hand if I wanted, and will carve a ham/beef/lamb joint with whatever makes sense for the positions and bones involved probably swapping hands before repositioning or spinning the carving platter. Writing sucks with either hand but right is better. Can solder with either. Hammers, saws, drills, chisels... whatever makes sense for the direction and position, though will typically go for right. Walk the dog (40+KG of German shepherd who loves chasing some rabbits, pheasants, hares, squirrels, deer, cats... and gets to full speed within about 2m, his lead being 5m, and we live in the country with loads of those all around) with either. Guns are around 80%, though that gets weird as I am neither eye dominant (the trick where you point at something with both eyes open, close one and see what goes varies depending on the hand I am using, matching sides for the curious). Swords... if I can have two I will but probably mostly right, certainly most practice done with it and don't even know if I could reliably do the whole arm, neck, leg, heart/liver and twist routine with my left). Toothbrush is either/swapping. Fist fighting then either are good for gouging out someone's eyes, deflecting or catching things. Computer mouse is usually right because that is how they are set up if you want anything fancy on them but if someone is left handed I won't swap around.
As far as forcing people to use another that is something that intrigues me and will occasionally read up what goes there. Can have some very interesting effects. My grandma was likely forced but they seemingly stopped around here in the 60s, didn't know it stuck around for that long (albeit at seemingly a far lower level) for others.
This bloody thing that I have posted a picture below has for my whole life frustrated me to the maximum. I have had numerous fights with it in my kitchen and it normally always wins. Its impossible to use if you are left handed.

That is more likely because I have not seen a good one of those can openers of that design in about 20 years.
They always seem to use the cheapest and nastiest steel that flexes just enough that while it technically works it does not work.
I don't know if a left handed version of that design exists, much less in good form, but you can do better with one of the nice razor edge ones that takes the whole top off rather than cutting a circle in them.
Still leave the can on the counter and have it spin there (I know old ones you could hold it up but not the new ones), you might also try either crossing your wrists or going from the back on the left or if you can risk it/also need to drain something then upside down. That or go for complete decadence and get an electric opener.
i use my left hand to take out the frustration in me.
Is that because it is so weak and uncoordinated that it feels like a) someone else doing it and b) is unlikely to hurt you?
