master/slave is an analogy that is used in technology which has an obvious origin and personally has always made me slightly uncomfortable since I first heard about it with reference hard disk priorities. Similarly the terms male and female make me slightly uncomfortable with respect to cables and sockets.
However, master in the context of git has no connection to the concept of master and slave. They are two different words with different meanings. So to answer your question yeah I think there is a line and it is somewhere near to that drawn by master/slave but nowhere near that drawn by master as in the concept of "original".
The thing here is that master has meanings that exist outside of the context of master/slave. Yes, slavery is wrong, and hopefully everyone agrees, but there are no slaves in GitHub. There are no slaves when it comes to master records. Erasing the word master from our language isn't about healing, it's more akin to forgetting or denying the past, and everything that could remotely be construed as having a connection with things we shall not speak of.
As for male and female connectors... It seems like an apt analogy, no? And uh, when it comes to male and female connectors, they are both equal, they both play a part, neither is better than the other.
> To allow for two drives on the same cable, IDE uses a special configuration called master and slave. This configuration allows one drive's controller to tell the other drive when it can transfer data to or from the computer. What happens is the slave drive makes a request to the master drive, which checks to see if it is currently communicating with the computer. If the master drive is idle, it tells the slave drive to go ahead. If the master drive is communicating with the computer, it tells the slave drive to wait and then informs it when it can go ahead.
This pattern of truth flowing from one agent to another is called the master/slave pattern.
It is the simplest coordination pattern there is, which is why it was used to control people doing menial tasks. We agreed it's not a good idea and no longer deprave people of agency (as much), but it still remains the most simple coordination pattern.
