Why? I think that slavery is bad only if the slaves are people. I want machines to be my slaves! (non-sentient machines only, dear future AI overlords!)
Are we going to remove "duplicate" because we can somehow imagine that genetically identical twins are offended by this?
Are we going to remove "admittance" (inverse of impedance) because people will be uncomfortable when reminded that they weren't admitted to their first choice institution?
These are all equally ridiculous to the master/slave debacle.
As far as "uncomfortable connotations", would you agree that that's a subjective claim?
I don't like that forced slavery is a thing, but I'm capable of handling context-specific word meanings, and of not getting emotional due to alternative meanings.
Your use of the word is violence.
