Yeah the original line, which you can still read here: https://medium.com/@SFyimby/wow-this-is-really-demeaning-ac316069c3fe#.oqbwxuy23, creates an equivalence between a 6 year old, a bar tender and an old woman. (Medium threading for this conversation isn’t going the way it seems like it should.)
The author should just take it out. It’s not at all necessary for the essay. It’s a throw away line anyway. Switching bar “maid” out for bar “tender” makes it less aggressively misogynist, but why pick any two categories of adult and equate them with a child? No matter who you pick it’s insulting.
