I do think dropping master is absurd, since it in no way implies slavery or any such thing. master mostly has uses that are entirely inoffensive, unless post-graduate degrees are racist, for example.

But I do think there is some merit in moving off the idea of white is good and black is bad. There are some good arguments that we shouldn't bestow magic powers upon words, but there is also a lot of merit in the idea that these words affect our perception in negative ways and there is really nothing lost by shifting to equally good alternatives.
