Git has nothing to do with that (not that master-slave is wrong).

> master-slave metaphor is both technically and historically inaccurate

How can a metaphor be historically inaccurate? The whole point of a metaphor is that it's evocative, not real. A slave DB following what the master DB is doing is a good metaphor. Where is the historical inaccuracy there?

Changing hard coded values costs a lot. I still have scripts which reference both `master` and `main`.

And we've gotten to the main issue. This whole thing is about making white-knighting white Americans feel better about themselves. There was no outcry from black people saying they can't program until Git changes its terminology.

Not to mention that slavery has nothing to do with racism. This is just an American-centric view. Historically people enslaved their own kind. Getting slaves from other continents is a relative recent thing in the grand scheme of things.
