Once upon a time, lefthanded people were treated poorly. For example, when they were taught to write in school, their left arm was tied behind their backs and they were forced to write with their right hand.
Though that isn't an issue today, lefthanders still face issues. Among these issues are the practical problems of being forced to use equipment that is aimed at righthanders. Which can cause problems regarding handling said equipment.
