I have the feeling that I might be racist.
Could you tell me more about the reasoning behind this?
You are a white man and you would never understand.
I understand your problem.  It is unfair to be racist against people for how they were born.
I know I'm just venting. It's valid for you to learn about your privilege.
I understand the message you're trying to get out there. But having these feelings of being racist is a bigger problem. If you are feeling this way I think you should seek some help in getting this out of your mind.
