Earlier quoted context omitted.
> Effectively pushing against the idea makes one a "racist" or a "white supremacist" as far as I can tell. Your wording is a wee bit vague. There's nothing wrong about pushing back on the notion that if one is white than one is guilty of crimes committed in the name of white superiority (because that's actually racist too). But it also doesn't discount the fact that racism is still very much a problem.
I am not vague. What is vague is the shadowy threat of being called a racist for stating ones opinion while having the wrong color of skin. It is a problem. Just a wee bit.
One's opinion should stand on the words/ideas behind them, not what one looks like. Getting called out for that is bullshit and should be disregarded.
Part of my confusion is also that I don't feel the threat that you mention. I'm also okay with being challenged and with being wrong. I think the key is to try to engage with respect and be prepared to listen to what the other party is trying to say -- and assume best intentions.
