The Grand Nagus sexually assaulting women, especially Kira, is never actually fully addressed.
Yeah, that was a weird one. In DS9’s pilot Quark touches Kira and she threatens him (“if you don’t take your hands off my hips you’ll never be able to touch anything with them again” or something like that) but when the Nagus does it in season 2 it’s played for comedic effect. That irked me too when I rewatched the episode recently.
