Honest question: what is it that happens to you when you read the words master and slave in the context of computer science? Slavery is horrible and so is killing, but I do not shed a tear whenever the words 'kill/terminate process' appear on my screen - I don't get visions of beheadings, I don't associate it with the act of ending a human life. It's a safe bet to say that no one reading about computer architecture today suffered as a slave, so saying this terminology triggers you is akin to me pretending to be bothered by loud noises because my great-grandfather went through war.

When you hear about a master/slave relationship or a male/female connector, you know immediately what is being described, which is pretty good for a method of communication. If you are unable to interpret words based on their context, I'm inclined to believe it's not the language that's the problem. I doubt that's the case though, I think these manufactured outcries are attempts at social engineering and moves in a game of power (controlling language->discourse->thought).
