I think it's interesting that people who don't really have any specific experience feel they must impose their opinions on us (i.e. the pediatrician and many, many of the CC people I know). I've always felt more comfortable with "black" because that's what the people I did know used.
I'd have loved to ask a few of my students--the people I spend the most time with
--but I don't know. I don't know exactly how to say this, but I this this will be the best I can do. I don't want them to have the burden of being my teacher in some of this--I don't want them to be forced into the role of being a representative of their culture. Some of them might enjoy that role, but it's practically impossible to tell until after you start asking questions.
Thanks, ahisma, ggman and arkasha!
