Feel free to agree or disagree.
I'm noticing some confusion over when to capitalise "chojin" or not. To me, this is not a proper noun, but a common noun. It works I the same way as "a human", "an alien", etc., which is why I've been systematically correcting it in articles.
We've not got a rule yet that uniforms this, and various editors - over time - have "fixed" from one to the other and back again. I'm proposing just one be used, with my suggestion being the lower case.
