On rare occasions, there is opposition to the suggestion of left-handers using their natural hand to play shamisen. The conversation once reached an aggressive level, insinuating that left-handers were insulting and destroying the Japanese art by playing with their natural hand. Ironically, those who decried left-handers were foreigners of beginning-to-intermediate skill level.
I often wonder why some folks are so violently opposed to others simply wanting to play with the hand they’re naturally born to use. Like all overreactions, it usually comes from one’s personal insecurities.
