I would suggest you GTFO ASAP. I lived in that part of Wisconsin (for a short period of time) 20+ years ago. I tell people, had I stayed, I would have been either a) in prison, or b) dead. These people, you cannot deal with. You're wife is a forgiener and your children mixed-raced, it's only going to get worse. I was from a big city and was harassed constantly when I lived there.
