The key word in there would be “evidence”: take the example of “oogling” female employees hulla-ooping. You can prove that they did hulla-oop, but not that the way others watched them was sexist.

Proof is a huge issue with sexism in general: anecdotal, or separate cases for discrimination; expression of consent when it comes to rape, etc. I wished organisation handling such issues focused on provability in court, rather than awareness.
