The use of that term in pretty much the whole English-speaking world is racist. No ifs, not buts. But one place it is not, is Papua New Guinea. Sure, they speak over 800 different languages there but the pidgin English they use, "Tok Pisin" (Talk Pidgin) specifically uses the term "pikinini"- note the spelling as well - to reference a small child. A boy or a girl. Use of the term pretty much anywhere else is actively being racist. It's not a term that "accidentally" falls into one's vocabulary in this era. Even in the early 1970's reading some well-known books of the 18th and 19th centuries (or having them read to you by a teacher) have that and other racist terms - and not just of those of Sub-Saharan African descent, but Asians as well - we were told they while that term was common when the book written, attitudes change. Sure, it wasn't said like that to a bunch of six and seven year-olds but you get my drift. Under no uncertain terms were we to use those words. Letters home to parents sort of thing. Anyone that uses it is knowingly being racist. Nobody cares if you were "born in a different time" any more. This isn't the late Victorian Boer War era. That's over 125 years ago. And even if you're eighty, you've had at least fifty years to adapt.
