That's good to hear, Seth. It's how people say things and in what context... it can be done to any description. Tone matters. 'Bushman', 'Aborigine', 'Bedouin' et al are never used by me in a negative context. I have great respect for those that function in harsh environments, productively using what they have available. If you see me using them, it is always with respect.
I do not consider those groups as lower in social status that have less resources available.
Mongolians have the same problem, it seems. I don't ever want them to stop calling themselves 'Mongolians' because it is seen as derogatory.
