I read somewhere that in certain places, "female" is used as a short form of "female dog" which in turn is used instead of a non-DIS-friendly word.
I'm really torn about giving in on this one, though! There's nothing actually wrong with the word itself, and people not in those places have no clue that other people are using it meanly. To me it feels like deciding nobody could say "blue" anymore, because somebody somewhere started using "blue" in place of a racial slur. I know language evolves, but only kind of by majority vote, and I'm not sure the majority even know about this?
