"Chinaman" is not inherently/originally a slur, but seriously who says that today? Even Englishman, Irishman and Frenchman sound slightly old-fashioned to me -

"Chinaman" is not inherently/originally a slur, but seriously who says that today? Even Englishman, Irishman and Frenchman sound slightly old-fashioned to me - surely you'd rather say "He's French" than "He's a Frenchman". It's one of those words you certainly shouldn't be offended at finding in an old book, or not even if an elderly person uses it, but if a young person uses it then he's probably dug it up deliberately for questionable political reasons.
