You can’t put this solely on the fans, writers make characters loveable or off putting. Women characters are very often written in a way that make people hate them. Skyler from Breaking Bad is a good example, she’s hated because she is only shown when she interferes in Walters life in some way. We know what Walter does for fun, but we never see Skyler do fun things and thus feel less sympathy for her, even if the ways in which she interferes in Walters business is almost always justified while Walter destroys much of her life.
