It makes me sad when a secondary meaning, which does not even overcome the main meaning in usage, becomes an obstacle for the normal use of a word. It's like seeing a rainbow as a sexualized symbol not fit for children, because it also happens to be used by LGBTQ+ community. (BTW, since you're a Brit: did people stop using the word "fag" to refer to a cigarette?)
I mean, it is sad. But unfortunately that is what happened with "master", "slave", "whitelist", and "blacklist". No reasonable person construed these as offensive or having any implications about the wider world. But there are people in our profession who are determined to take offense where none is given, and unfortunately they got their way.
Well, "slave" has a pretty direct main meaning of an oppressed person doing forced labor. The word "master" is much milder in this regard (compare "master's degree" and "slave's degree"). The word "nonce" in normal usage seems even more removed from any pejorative secondary meanings.
