hi there! i don’t think it’s possible to read the text critically, as a product of its cultural context, and not arrive at the conclusion that the authors were influenced by a socially ingrained prejudice against indigenous people (especially considering the western genre’s influence on sword-and-sorcery pulp literature). luckily for us, gygax explains this himself in a forum post from 2005, comparing the position of lawful-good characters who are obliged to slay evil characters (where evil, above all else, is a racial categorization) to the position of american soldiers killing not only native american warriors but women and children (“nits make lice”). again, i think all this is quite clear from the text itself, but this interpretation agrees entirely with gygax’s own. take it up with him!
