Cultural Appropriation and other issues (Patreon)

So, for Lunar Episode 2 I have always planned to introduce 6 new characters: birds. 

I wanted them to be a "vaguely tribal" culture so I could explore what would happen if a reasonably advanced race such as those in the Lunar game came across a relatively primitive race. I am sure something interesting would happen, but I haven't written it yet.

Now, immediately, my default when I think about "vaguely tribal" is I tend to think towards American Indian culture. I have spoken to some people about it and have been strongly encouraged to veer away from that as much as possible because the American Indian culture has been exploited enough.

My immediate thought is I could refocus onto Scottish heritage, the benefit being that I personally have Scottish heritage and so I couldn't really be accused of too much cultural appropriation, plus birds in kilts sounds kind of cute. 

Another option would be Maori or Pacific Islanders, this would have the obvious same problem with cultural appropriation, but certainly less well known and less exploited than American Indians. 

Finally, I could go for a more generic tribal solution, the problem with this is I fear it would default into a general feeling of American Indian culture and so we're back where we started. 

Keen on your thoughts, the poll below is to help stimulate your ideals =D
