I do use the word Shaman, but only as an (over) simplified method of communicating an idea and never as a word of definition. I don't know about other countries, including the US, but here, in Canada, many healers and medicine people are referred to as Shamans and it is not considered dis-respectful. It can, in fact, be a term of respect. I was given a Cree name "Omisimaw Awiyak Kamamahtawisit" which loosely, very loosely, translates to "Sister Shaman" in English. This, BTW, was not a "spiritual or sacred" naming, it was given as a term of endearment, so it is not disrespectful for me to use it if I wish.
