So much of his behavior would not be tolerated if the man looked like this:
I dunno, Rumple isn’t exactly stereotypically dashingly handsome, and folks still love the crap out of him. Hook might have a bit of a “dirty old man” vibe if he was older and still said some of the stuff he does, but I think at the end of the day, pirates can get away with a lot and still be considered badass because they’re pirates. They’re not meant to be polite. 😉
People’s views of Onciverse Hook can be quite polarising. You either think he’s completely shallow, or incredibly deep. I’m the latter, but can see how others could take him at face value and be turned off. It’s not really that different of a situation to Rumple. People either think he’s the ultimate evil, or the ultimate candidate for redemption.
