The term master/slave of all terms is widely used and established in many fields of EE and CS especially in networking. I was exposed to it since I was a college student endless times and never ever thought of it having any kind of racist meaning, and again, I have a dark skin myself. The term is used in thousands of seminal textbooks and published papers by many great scientists who worked for decades and retired without even thinking that this term could map to the history of racism in the US or anywhere else. What's next? should we organize book burning parties and burn the textbooks of Leslie Lamport and Donald Knuth because they contained the master/slave term?

These lousy radical groups are only brave at the things that don't fight back and are very dedicated to solving non problems and the rest of us is obliged to either bow to their irrational nonsense or labeled as racist by their primitive mob mentality.
