I really really implore you to read up on this stuff more. It's clear that you haven't approached the subject of racism with humility, humbleness, or even the possibility that you aren't the best person to know about the issues that other people face.

You are right in a way, I am discounting a person who hasn't felt the effects of racism to fully understand racism and give a good opinion on it. Which seems like a pretty good benchmark? I think your response to this enforces that those who haven't felt it aren't good judges of it.
