I was so focused on the aspect of misogyny that I didn't realize how ableist this term is.

Meh.. manual does not mean hands.. or if you were trying to be satirical, please don't turn HN into reddit.

Nitpick: yes, it does. man- is a root for 'hand', and 'manual' as a noun was a term for 'handbook'.

Oops.. looks like my etymology has long been forgotten. thanks for correcting.
