Here's why:
* Subjectivity: What's considered offensive varies greatly based on culture, context, personal beliefs, and individual sensitivities.
* Context: The impact of a word depends heavily on how and where it's used. A word that's shocking in one situation might be perfectly acceptable in another.
* Intention: The speaker's intent plays a huge role. Using a word to insult or demean is far more offensive than using it in a casual or humorous way.
Instead of focusing on "badness," it's more important to consider the impact of your words and strive to use language that is respectful and appropriate for the situation.
If you're unsure about a particular word, it's always best to err on the side of caution and choose a different option.
