I've been to Mountaineer stadium more times than I care to admit for SU games. Used to be close when I lived in northeast Ohio when we played there every other year, and I went down a couple of times when I was a kid with my dad in the 80s, as a reasonably close road trip.
You won't see a more raucous, fiesty crowd than what they have -- and they have true animosity for Marvin Graves and Troy Nunes, for plays that occurred years ago. Inside the stadium, its an uncomfortable experience.
But you honestly cannot meet a nicer group of hospitable fans outside of the stadium. On numerous occasions, we've parked and had WVU fans parked nearby unsolicited invite us to tailgait, and insist that we have some food, etc. One time, a little kid said something fairly harmless to us since we were decked in SU gear, and the dad wigged out -- offered us beers and was extremely apologetic for his son's behavior, saying that he didn't want that to be our perception of WV fans.
There's no doubt that some of that racial sentiment existed during that time of american history -- but it just seemed like sloppy writing to me. Wasn't West Virginia part of the union? Isn't that the whole reason we have a "West" Virginia, compared to the actual state of Virginia, because they didn't side with the confederacy and it split the state?
That, in tandem with my own experiences there and seeing how friendly the fanbase is, makes me believe it when they express sincere surprise that they are being portrayed that way in a fictional movie situation. Can I envision them being that rowdy? Sure, for football purposes. But that racial? I think they were the victims of being mis-portrayed, and that it was just "lazy" writing to make a ham fisted point by exploiting a trope, given that they were our most "southern" opponent.
