Interesting metaphor. I’ve never really gotten that idea – I’ve never seen the connection demonstrated between the “big stuff” and seemingly innocuous things like ‘main’ vs. ‘master’.

Also, a lot of this feels misplaced. IMO, the root problem is one of attitude where the minorities are viewed as less-human, not deserving of equal treatment or equal rights. Change will happen as those attitudes shift. I haven’t seen a connection demonstrated between those attitudes and…well, pretty much any terminology issue that’s come up in recent memory.
