Usually I don't cuss or use profanity.
Part of it is how I was raised. My mother did not approve. And in most personal and professional situations, dad didn't use language that way. Don't misunderstand, Dad used language eloquently. He had been a classical music DJ and had a remarkable voice. He also did ham radio. Stick a microphone in front of him and he was amazing.
Then there was a bit in Danse Macabre where Stephen King was talking about profanity. The line was a woman saying "Oh shit, I stepped in doggy doo-doo." It was the perfect summation. The word "shit" was meaningless in that context. To me it was obvious. The more someone used profanity, the less they actually had to say.
I wanted my words to mean something. And if I swore, I wanted people to pay attention because people knew I usually don't do that.
I don't care if you do. My choice shouldn't control you. And your choice shouldn't control me.
That choice is what makes us individuals. We say what we want. My choice of pronoun shouldn't govern you. You not empowered to decide what topics I can and can't speak about. And yes, I should be able to insult you. But if you don't like it, you can walk away.
Actions are a little more complicated. There we do have restrictions best summed up as measurable harm. I shouldn't be able to hurt you, steal from you, or damage your property. Likewise, you shouldn't do that with me.
Even then it's about choice, just a little more restrictive.
Liberty is choice with responsibility. It all starts with choice. Do you choose to speak clearly or make noise? Do you choose to act with honor? Do you leave the place a little better than how you found it?
Simple choices with profound consequences.
