Quoting: "It’s as clear cut as this: Treat all women like you would treat Dwayne “The Rock” Johnson." and "But definitely don’t hit on her. It looks like she could kill you with the chair you’re sitting on."
It's really that simple.
It possibly devolves to "behave like a bumbling star-struck fool around all women".
Or possibly to "treat women like goddesses". Example: if I run a cafe, and idolize "The Rock", should I give every woman a free coffee and muffin, because that's what I would do if "The Rock" walked in?
People who are famous get all sorts of unwanted attention that would easily amount to sexism or sexual misconduct if it were lavished upon a person because she's a woman. Fans want to get near you, touch you, take a picture with you and whatever.
Yeah I'm going to ignore this advice, I think any sane person ought to do the same. Or at least if your mental model of the Rock consists of more than generic tough guy in some recent films who may have hit people with chairs in the past or something.
"Hey, how much can you squat?"
