I always think this gets more obvious when you live in another culture:

I don't cuss a whole lot. Even when I'm upset, the words just don't come out. I have no ethical objections to most cuss words. A word is a word is a word. I only have a moral objection to language used to hurt people, degrade others, and purposely offend. Obviously cuss words can be effectively used towards that purpose, but cuss words are not the enemy. I can hurt, degrade, and offend without dropped any particularly word; it's the set of words. The overall organization of my thoughts that can hurt people. We don't need to be afraid of a particular word.
