Just because you can say a thing doesn’t mean you should. Words are like minutes. Once spoken in a moment it is gone forever. You can’t suck it back in your mouth. You can treat it like you never spoke it, if no other human heard it.
Written words are a bit different. If you write a word you can delete it, but once it is published and read it it is like a spoken word.
You would think that with the permanence of words that humans would be careful with how they toss words around.
You are free to use words in any way you want to. You are not free from the consequences of releasing those words into the universe.
Be responsible in the language you choose. Not only with other humans but with yourself too.
