Did you know that “Centuries ago, the Catholic Church declared left-handed people to be servants of the Devil?

There are also quite a few superstitions about being left-handed. It wasn’t until we realized, in the last century or so, that there are legitimate biological reasons for left-handedness, that people were no longer forced to use their right hand. I’m not the only person who sees the parallels between being left-handed and being gay. You can read a lot more about left-handedness at this site.
