Your examples are actually supporting the argument. White lies are innocent, not so bad lies, much better than black lies. White washing is making something look better than it actually is, that is: make it look white = make it look better. And the only one that doesn't automatically use "white" as good is "white collar", but that is because here the distinction is between "white collar" and "blue collar".

Haha you’re right. I never thought about it this way, I just took words as whole, and these words are all negative (in my mind). Although technically you could say the same about “blacklist”, people want the same concept (blocking, which isn’t necessarily negative) but don’t want to associate it with race.
