My problem with swearing has nothing to do the words themselves. Words are nothing but sounds that the brain perceives to have meaning. Words are neutral.
My problem with swearing is that those words are often stand-ins for better, more effective words.
To your brain, there is no difference between speaking and thinking (and writing for that matter). To do one effectively is to do them all effectively.
As Jordan Peterson says, “You need to learn to think, because thinking makes you act effectively in the world. Thinking makes you win the battles you undertake. If you can think, and speak, and write, you are absolutely deadly. Nothing can get in your way.” (1:50).
It’s hard to understand this logic if you haven’t developed the skills, but once you do you’ll never want to go back.
