Left-handed Violin Playing - Which hands to use ?
Since most people are right-handed, why do we perform violin fingering with our left ?
Shouldn't our more articulate hand be used for the intricate fingering, while our "worse" hand does the simpler bowing ?
-In other words, why don't we hold the violin to our right shoulder, and bow with the left hand ?

Very good question! I remember asking this when I was first learning as well.
The simple answer appears to be: tradition and economics.
Violin has been played this way for many years, with some exceptions. Orchestras of various sorts in particular often prefer players who look similar in order to not distract from the music.
Most of the violins and violin accessories out there, including bridges, chin rests, and other things are made for a standard violin. Left-handed violins exist but are more scarce and therefore more expensive.
I found an interesting link by a professional violinist and teacher, Ryan Thomson. He discusses how difficult it was for him to switch from playing "right-handed" to "left-handed" and some of the bias he found in the musical world when he succeeded in learning to play again professionally, left-handed. http://www.captainfiddle.com/leftmusicmaking.html
I know this probably isn't the most satisfying answer and it's possible others may know something I don't. (Please comment if you do and share your knowledge!)
