I don't believe this World can't be seen exclusively in a Black and White perspective. It is just like Good and Evil. Terms like these tend to be pretty generalized. So, もっと見る like Gray/shades of Gray and every other color depending on the subject. We are usually able to see them for a reason !!!!
I take things as a case によって case scenario. Many things can be view in gray areas and many things can be view with a black/white mentality. Sometimes both could be seen on a single situation.
Example: Racism is wrong. No matter how あなた slice that it is wrong. Sexism is wrong. That being 発言しました some people joke about their races and sexes all the time with their フレンズ and be completely harmless. Context is key. Without knowing context あなた are not open to a variety of viewpoints if あなた only judge from a black/white standpoint. That being 発言しました the same thing could be seen if あなた only judge from a gray standpoint. If someone is seriously racist and sexist and they are truly a deplorable person then that person is an asswipe. There's no getting around that. Being a racist/sexist,(any close minded form of thinking) asshole is unanimously bad. Just because the reason they became that way might have not been entirely their fault that doesn't change the action. No one should be entitled to think they are the superior sex または the superior race.
But this is only in philosophy. In science many people in the field allow for gray situations just in case their initial plan isn't as concrete as they presumed in the beginning.
あなた have to be knowledgeable and open-minded only then can あなた truly be a wise person. That is my viewpoint at least.
