You can’t erase racism overnight. It happens over time. I know Hines Ward meant well. There are lot of half Koreans who are famous, like Hines Ward, Liz Cho, Kimora Lee Simmons, Moon Bloodgood, and Mark Polansky
Personally, I don’t think it can be “eliminated” at all.
God gave us many vices to overcome. Like jealousy, gluttony, etc., racism is a built in human trait. Some folks are prone to exhibit it more than others, just as some folks tend to be super jealous and others not.
It just so happens to be one of those human traits that we can find comfort in with others. That’s what makes it tough to discourage.
Like drunks in a bar who encourage each other to drink more.
It will never go away. If we know this about it, its a whole lot easier to deal with, IMHO.
