Gypsy is indeed a slang term for those people then it should be removed from use on this or any other Mountain. how can this kind of racism still be allowed to be published in this day and age.
the fact that you don't mind throwing it around has no bearing on it's meaning and the inappropriateness of your use of it.
I suppose you could claim ignorance of what you where saying and that could be viewed as a viable excuse for your casting racial slurs against others. But now you have been Educated as to the nature of the offensive use of this word,
now we will see what the nature of your group really is.
will you seek to live in harmony with others or will you continue this abusive treatment of minorities with these racial slurs.
now we shall see what is in your hearts and minds.
we now only have to wait and see what minority group earth first will honor by naming a mountain for them in some derogatory fashion
