Good or bad is no scientific category. All you can say is that something hurts or is joyful. And then a good guideline for actions is the old saying: "Was du nicht willst das man dir tu, das füg auch keinem andern zu" (the German is better than the English equivalent). If someone keeps hurting me by - dircetly or indirectly - communicating that I have an inferior mind because i am a woman and that therefore I should obey and subdue to male entities (whoever that may be), I let him know that this hurts me and also try to show him that this is not true.
