Until I was about 14 years old I always thought craftsman and other words ending in "man" were based of the word "human". Even the word "woman" has "man" in it. Can we stop pretending these words are sexist? It's even more bigoted to assume sexism based on use of a common term ending in "man". It's border-line insanity and people just use it to push other people around and further a political agenda.
