I'm a leftie too!
The Everly Brothers, Don and Phil, played guitar right-handed but were both actually lefties. They played guitar right-handed primarily because their father, Ike, taught them that way to avoid the social stigma and practical difficulties associated with being left-handed during the 1940s and 50s.
One of the many reasons I hated school from 5 to 16 was that we, a few leftie pupils, were regularly shouted at and treated like morons by ''teachers'' who thought only righties had any intelligence. I left as soon as I turned 16 in April of 1981, instead of waiting until September! Didn't bother collecting my stuff from the locker or saying anything to anyone; I just didn't go back!
In Worcester, some years ago, I found a shop that claimed to be for us lefties, with leftie scissors, books, etc. I was excited, went trotting in, and the creepy bloke only had about 2 leftie items, everything else was for righties! I asked why he claims it's all for lefties, and he just smirked, so I walked out and never had anything more to do with him or his equally stupid shop!
Being a leftie and ''bad'' etc. is associated with religion, witchcraft and so on, by the self-righteous righties!
