Any word can be considered "vulgar" though. Society likes to create a list of words that are "cursed" and anyone who uses them are being profane/vulgar. I don't subscribe to that non-sense and the only reason I don't use those words on CC is because they have rules (they adopted the silly extrabiblical concept of "bad words" or "curse words').
I'll concede that in the context Trump said it, it was unwholesome. But I have a question... If he said, "Kamala Harris is a freaking female dog", would you feel equally shocked and appalled by his "vulgar" language? Or do you think it's somehow better/not as worse? If it's not as worse, please explain.
To be clear, I believe Ephesians 4:29 commands us not to let any "unwholesome talk" come out of our mouth. I can say he is wrong for letting unwholesome sentiments of Harris come out of his mouth but not BECAUSE he used words from society's list of 'cursed words', but because of Ephesians 4:29. Having said that, I'm human and sometimes let my emotions get the better of me and say and/or think unwholesome things just as Trump.
