I’ve been trying to find out how one proves one is not a white supremacist. I asked my Polynesian/Chinese/... wife and my mixed race children. They were flummoxed. So I called some exes (Muslim, Jewish,...), no concrete suggestions either. I’m seeing the Caribbean side of the family next week and will ask. I’ll report back.
You'd need to say frankly that, being a white person, all you've gained in your life is little the fruit of the work you put in it but mostly that of the centuries long injustice.
