I'm all for being nice, but the "rules" in the article are just plain stupid.
Any trans people who come here aren't likely to be offended by "breast" or "mother". The language has ventured into the absurd, and looks more like the article, and its prohibitions, were created by a right wing whacko who was ham-handedly wielding irony.

Which is, I believe, how the term "political correctness" entered the lexicon.
