There are many whites who think they are the ones suffering discrimination in our society, am I to accept their view of their lived experience?

No, I do not accept what they are saying, and I doubt you do either. They have a warped view of their lived experience, bigtime. I hope I am making my point here, you can’t simply accept what someone is saying is accurate, even of their own experience because we are all fallible human beings. All we can do is listen with an open mind, ask questions when we don’t understand, maybe offer an outside perspective and hopefully come to truth and understanding.
