Replaced occurrences of master/slave terminology with leader/follower 12 years ago
How about "underling/overlord" or "dictator/subjugant" or "enforcer/oppressed"? What about "worker/parasite"?
Mayhap "strongman/peasant" or "oligarch/human rights violation"?
I know, let's all use "duckspeaker/thoughtcriminal"!
