Not my lifetime, but my Mom's sister was initially forced to write with her right hand, despite being left-handed. Since they went to Catholic school, it was taught, as fact, that being left-handed was something something Devil.
When my Aunt started Grade 1, my Great-Grandfather died a couple weeks into the school year and bequeathed some money to the church and school. The family would not give it to them unless my Aunt was allowed to be left-handed.
Amazingly enough, the Priest, upon prayer and reflection, determined that being left-handed wasn't a problem anymore. Isn't that something? That's how my now 78 year old Aunt changed science at Blessed Sacrament when she was 5 years old.
