QuoteWas lefty, had aversion treatment by childminder as a toddler (yes, punished for being me), and now use my right. The written product from either hand is poor.
I am also a "lefty", but don't know that it has anything to do with being trans. I had a grade 3 teacher who tried to force me to be right handed, she'd walk around with a ruler and when she saw someone using their left hand she'd rap them on the knuckles with the ruler. That messed up my writing too. I do most things with my left hand, some with either, but some things I was forced to do with my right hand because tools, baseball gloves etc. were not readily available for lefties.
