There's a reason that we don't go into people's homes and tell them how to live. We may not know their problem, and what it's like, so how can we know the solution? We don't say to someone who is hurting 'I know what's wrong, and it's nothing, so you shouldn't complain or be bitter.'... And finally, for those who are angry at people who are sad from suffering, and racism, and stereotypes and prejudices - this is their pain. It is ok that they have pain, and that they are dealing with it the way they need to, and the way we need to. If you are thinking of yourself, it won't make much sense, because it doesn't have anything to do with you. Think of them instead. And if you really want to see someone smile, and not suffer, think of a way that you can bring them joy.
