i don’t care if “dean would sexually harass people of any gender” is the route you want to go with bisexual headcanons of him, do whatever you want (but be aware that this is a biphobic stereotype!), but from a media literacy standpoint this is a nightmare conclusion to draw from the beginning of 2x17, even more so if you end up at just “dean loves men” like that post did. you shouldn’t take madison’s “you get a few scotches in him, and he started hitting on anyone in a five mile radius. you know the type.” and deduce that the use of “anyone” equals gender neutrality, equals bisexual dead boss, equals bisexual dean. because that is obviously not what this scene is communicating about dean and his behavior.
dean is directly being compared to a drunk flirt who routinely hit on anyone available and who hit on madison specifically so many times she’d come to expect it, because she knows that he persist even after she refuses him, which you can see at the start of the episode. you can’t ignore all the negative connotations of that just to validate your own assumptions about dean, it’s disingenuous. beyond that the boss was in all likelihood a heterosexual man, the episode gave no indication of him hitting on men, so “anyone” just means anyone in his dating pool, aka women who go to bars. and even if i agreed to play the linguistic gymnastics game on this and assumed the boss also harassed men that still wouldn’t make it a dean being bisexual scene. it’s still a dean is just like madison’s boss who didn’t stop flirting after she said no scene.
