If you could permanently ban a word from general usage, which one would it be? Why?

I want to ban bad or abuses words from general usage to harm the reputation of any individual and is the main cause of fighting between people.

Presently, the use of abusive words may increased amoung people during fighting and enjoying. These abusive words are responsible in creating tension in the society or city.

We should reduce the use of abusive words that decreases tension and encourage good words to use among people in any conditions.
