True, but from the fact that someone is somewhat fluent in English, it doesn't follow that they can easily infer the meanings of such context-free and technical terms. In fairness, though, I don't know the extent of this problem, and I can't really speak for such an audience. I do know that has been, well, general, unspoken policy to be at least as inclusive in other contexts, even when the nature of this site would kind of obviate the need to be inclusive in that particular way.
