This is strange.
I, too, have “Native” (Amerindian) heritage, a direct maternal line. Yet I have never taken personal offense at any religious teaching, or philosophical position, which places either my ancestry or my race, my nation or my language in inferior position or moral disrepute. Beliee as you will. “It’s a free country.” (Though much less free than it could once boast.) I was taught very early in life, “Sticks and stones may break my bones, but names can never hurt me.” Of course there are exceptions, some sticks and stones do not and cannot break bones. The maxim holds true generally.
There are many areas of society - the military, some sports, martial arts, construction, transportation and roads - where all sorts of words are used. It’s better to train oneself to get used to it and accept it for what it is - one language register out of many - one social context of many - and not take differences in language registers so personally.
