I think it's the user that makes a connection with racism. I always thought blacklist and whitelist was based on color absorption, black absorbs and therefore doesn't let through anything. White was simply the color opposite to black.
I assumed master/slave was adopted from the idea of a master record. The main thing that came to mind is audio mastering, not people. Am I missing something about the origin?
It's nice to see changes that make things more clear, however I wish political correctness was not a factor.
Are orphan processes and brainfuck next?
