Words have established and generally understood meanings within populations. They are not 'just words'.
They are vital communication tools. And if some people change the meanings of words to mean the opposite of the words original intended meaning, it means that those people lose the ability to communicate clearly to others.
It is not respectful for a group of people to forcibly change the meaning of words that another group need for their own unique descriptions. It is not respectful for people to force others to use meaningless words just to make another person 'happy'.
