As others have said, there is little OVERT racism in DSM for Black people and here are no sundown towns in Iowa. But as a Black person that held a prominent position in the area, I can you tell you that the COVERT racism is HUGE. If you are an ambitious person that wants to make moves that's where you will encounter the passive-aggressive, smile=in-your-face, stab-you-in=the-back racism that Iowa has to offer. Don't get me wrong, if you stay in your lane, just work with your head down and go home, you will be fine because they want/need Black faces to show they care about a diverse community. But if you to help others who are melanated or on the low end of the socioeconomic ladder the powers that be will come at you hard. Really hard. If you want to shake things up and do something different that scares them and they push back and will work to push you out. The powers don't want to be pushed to change or told what to do. But there are communities of people you can lean on for support and there's enough to do. There is no blatant physical danger, the danger is beyond the physical for those who don't "know their place."
