jeez, what are we going to have to rename the master and slave cylinders in our vehicles.

WSIWG, not quite sure why you believe that people of colour would have such tunnel vision that they would believe they are the only ones qualified to own the terms "master" and "slave" and as such, somehow be offended. The terms has been used since biblical times, as I'm sure you would be aware and have nothing specifially to do with race.
