Agreed. Words are what made us different than animals and words describing abstract ideas made us better than other primates. Words are maybe the strongest power we have
Given the way humanity works, words generally do and should have power ("profane" or otherwise). If they don't, what's the point?
On profanity, to me it's a set of special words to break out for emphasis. If I just casually use them, then they lose value as emphasis. If those words were just as mundane as others, what would be the point of their existence?
