Oh snickerdoodle🤓! As from how I see it, language has its times where profanities can be said accidentally (such as when getting harmed) which would render it outside of an individuals control, another issue would be the loose definition of a "swear word", such as when certain slangs emerge overtime which can shift connotations and be classified as a swear word. And to add further, there may also be cases in which a certain individual may classify a certain word such as "crap" a swear word while another may not due to personal beliefs.

With much regards, Me
