Eric, this article is filled with Liberal IGNORANCE. Christians are NOT racist. Just the opposite. Observing that there are mostly black and white and even Korean and Hispanic, and Creole churches, et. al., is NOT an indication of racism. Good GOD.
Have you ever stepped foot into a black church? I have. I'm not big on their brand of worship. It has nothing to do with the people. Yea, it's a helluva lot of fun to watch, but I am not into this style of worship.
Does that make me part of structural racism? GOD NO! It means I don't identify with their (black) religious culture. Korean, Jamacian, Hispanic, et. al. churches are the same way.
People gravitate toward the church where they feel most comfortable culturally.
Stop trying to label people with a "racist" label because they prefer one culture over another. THAT is the very definition of being a racist!
