OP: "What you will find is that people are friendly, as long as you look like them (white)."

P: "Of course everyone isn't racist, and most folks are friendly and accepting."

If these statements are equivalent, you have my apologies. English is not my native language. I think I will have to study for 10 lifetimes to understand.

"Some people are friendly only if you look like them" would be a more defensible claim. Probably that is true everywhere on earth.

But, the text of the original statement is about the behavior of Midwestern people [1] generally towards non white people generally.

[1] Not all Midwestern people are white in any case. Nebraska: 86%, Ohio: 82%, Illinois: 71.5%
