All words should be available to every American. How they are used is up to the writer or speaker - their taste, what they are trying to express, etc. Some words can be hurtful and one should be careful and thoughtful in their use.
But, imo, NO person.or group should be allowed to dictate how we use this most precious of all languages.
The same is true of our history, monuments, documents, and so on. Sometimes they are not pretty, but our.history is a matter of fact. And to grow and improve, we should try to learn from our history, not try to destroy it, or run from it like a.bunch of cowards.
By making such huge stink about the 'N' word, blacks have given the word a phenomenal power. It would never have had such power if they had simply left the word alone. In any case, the word will never go away. The huge amount of attention it has been given will see to that.
Finally, we've entered an awful place when, in this, the most freedom loving country in the world, any group thinks it should be able to dictate to the rest of our population how we use our words and language, or, what parts of our history we should keep or value.
