Master and slave

[Ahriman]

The key to language is communication and understanding. If there's a way to accomplish both while avoiding offense, I think that's the way to go. I suspect that master/slave when used in the industry context is understood in its technical sense and shorn of much of its historical baggage, but if it bothers you or you suspect it may be causing offense, then see if another phrase will effectively convey the same meaning and switch to that. Maybe it will catch on.

Right, exactly. Nobody should be offended by such wording. We can't just change everything because some people's feelings might get hurt if we don't change things. There's nothing logical about that.
