Growing up this was a big realization for me the other way. I was raised by evangelicals in Kansas, including going to a mennonite school for most of my education. As a teenager I realized how at my school, at my church, at basically everything in my family's shared life, there was not a single person with brown skin. Not even one. And worse, no one had real awareness of this, and would not understand how it could be any sort of problem if you brought it up. To them it was just the natural order of the universe that their world was purely white people.

There's plenty of evangelicals of every race, but overall the communities are very segregated. It was clear no matter their professed faith, in practice the community I grew up in was hostile to PoC.
