I guess my viewpoint is that while vulgarities themselves may not be immoral, I find them to be a "slippery slope" so to speak. Yes, you can describe a car as a four letter word or whatever, but how long before someone slips up and starts using that to describe a person, or a group of people, etc. Whereas while avoiding vulgarities will of course not eliminate hate speech, it cuts off a slippery slope avenue in my opinion of using objectifying language towards a person or people. And to be fair that may just be how I see things. For example, I don't drink alcohol. I respect that it's not illegal to drink it but all I see is something that has no real use and can easily be a gateway to other problems. I'm not equating using vulgarity with alcoholism but what I see is something that I don't see any use for, the rare positive uses of it are slim or nonexistent or can easily be replaced by less potentially harmful alternatives, and instead it just ends up a potentially needless slippery slope to worse things when that can be cut off much earlier. So I see your viewpoint now, mine is different, and I guess that's just how things are.
