I understand your perspective. I'm not against changing the term. We changed it in our product a few years ago (master-slave to primary-secondary) as well ... primarily because even if you offend one (current or potential) customer it's just not a hill worth dying on.
But to address your point though, I wish there was some acknowledgment by 'the SJWs' (as you put it) that even if the term is archaic and should change, the tech community simply used a descriptive dictionary term for a particular architecture, and therefore the term is wholly unconnected to 'white supremacy' or 'systemic racism' or 'unconscious bias'. But for many who raise these issues, there is no good-will or charity. And that's why there is pushback. Many people don't want to accept the position that they were purposely insulting other people when these terms were in widespread use.
