@matigo My dad was also born left-handed, and forced to switch thanks to the enlightened1 educational policies in place in Chicago in the 1930s and 1940s.
One consequence of this was that while they could force him to write with his right hand, and he too ended up an ambidextrous writer, it did not carry over to non-educational pursuits, and when he taught me how to hold a baseball bat, he did it the way that seemed natural to him. As a result, I'm a left-handed batter (and golfer too, for that matter) despite being right-handed in every other way.

I'll skip the <sarcasm> tags here this time.
