I grew up in the midwest, and discussed inter-racial dating with some young adult guys at that time (about 15-20 years ago). There was a sense in which non-white women just weren’t on their dating radar screen, like **Fuzzy Dunlop **reports. It wasn’t associated with any racial hatred, but more of an invisibility thing. Minority male/ white female dating was very common, but the reverse was much, much less common. I don’t think she’s making that aspect up. With enough research, you could probably find informative data about interracial marriages in the area that would shed some light.
There’s also the fact that minority women graduate from college and grad school at much higher rates than minority men. With the tendency of women to want to date/marry “up,” all high-achieving minority women face a conflict to some extent.
I’m not sure she needs to flee KC, unless she wants to for other reasons. But my advice would be 1) don’t waste any time on the non-decent ones she seems to be attracting. That doesn’t mean be extremely picky, but if he doesn’t pass a basic sniff test, don’t waste the time. 2) Find ways to hang out with people who didn’t grow up in the midwest. Staying in touch with her grad school community, getting involved with organizations that welcome newcomers, etc. may be ways to meet people with more open minds.
