Shooting thingies like guns, bows.
A left-handed gun wasn’t really heard of when I grew up.
I’m sure some existed, but I’d never seen one, let alone used one until much later in life.

I’m right-handed… but left-eye dominant. Actually, not just eye-dominance, but I have noticeably worse eyesight in the right eye, even with correction.
Being right-handed, I never really questioned it when someone handed me a right-handed shooting apparatus.
Not that I used bows or guns that much, but some just plain sucked to use and I only figured it out later in life.

Shooting from the left shoulder makes a lot more sense to me because that’s where my good eye is and my left hand only has to squeeze the trigger or release the string anyway.
Sight alignment is way more important.
Moving and pointing the thing with my right hand makes sense.

Many modern bows have very pronounced “handedness” in their very asymmetrical designs and are very awkward to even hold offhand and almost unsable.

I don’t mind righties’ break actions, that’s mostly ambidextrous anyway unless there’s a pronounced grip.

Righties bolt actions are a bit weird to cycle, you either reach around to cycle, or hold it up with the trigger hand. I’m kinda stuck… a lefty rifle is superior for me, but I’m somewhat used to righties.

Righties semi-autos kinda suck because of the gasses being ejected in your face.
I imagine full-autos suck more in that regard.
That and mag releases and safeties.
