Thanks for the explanations Mike, Glen and Magnus. When I was a child in the 1940s, and every other film to come out was a 'Cowboys and Indians', the latter were always "Red Indians". I knew of no other sort, and as for different tribes, well, forget it!

There is far too much so-called "Political correctness" in our lives thesedays for my liking. It's ridiculous. I prefer my coffee without milk/cream, but apparently it's not PC to ask for a black coffee, as we have done for as long as I can remember. One should request "coffee without"!!!!
