Mr C's fight for feminists everywhere is disappointing, it's as bad as anyone who says "herstory". (I will admit I've never seen anyone complain about the word THIS having his is in and demand we use THER instead).
I think a more important argument would be why is there just man-at-arms for Str users instead of two categories, while dex has 2 and int chars get to pick from 5.
But no, I guess some would rather focus on silliness to make no point.
