I might well be wrong but this kind of authority over the use of language seems to be much more US-specific than I've seen elsewhere, which you could attribute to the overall dominance of US people in the places where these discussions tend to crop up (github, HN, Reddit, Twitter, Tumblr, etc.).

I don't really know what to make of it except that these discussions about not using 'master', 'cop', etc. seem _heavily_ biased to the US perspective and current affairs in the US. I can understand it taking place due to the sheer cultural upheaval that has (quite frankly) been a long time coming, but my mild frustration about `US === the whole wide world` can take a step aside while we focus on the injustices fellow humans face.
