Why do people fall for folk they subsequently try to change? In some cases the “problem” with the person is nothing directly harmful, a sports fanatic or fangirl or flirt for instance, but in other cases it’s more serious, such as the abusive boyfriend. It’s as if hormones override common sense making us believe we can or have the right to change people into what we want. But if you (used in a general sense) know a person’s likes and dislikes already and that they’ve liked those things long before you came around, why pursue someone whose hobbies bother you so much? If a person's hobbies are so disgusting or distracting, it seems more logical to just avoid that person. I wouldn't chase after a Yiffer, for example, nor expect a longtime Furry to change their ways just for me.
Perhaps there is one thing about them they do find appealing -- something physical or mental such as looks or a skill - yet that alone is not enough, because they’re “flawed”. But are a person’s likes and dislikes, assuming it’s harmless enough, flaws? It seems akin to saying a person is flawed for liking to eat fish. In cases I suspect the person doesn’t really care for the other, looking instead for a doll they can mold into their own ideal. Thus, who’s the worse person, the flawed object of your affection or you for trying to force a person to be what you want?
