I'd suggest that you start a discussion on the article talk page, so that LuxNevada has an opportunity to show that Lopez's views are idiosyncratic (in which case the views should be excluded as undue, or at least attributed to him inline), or you to argue that he/they represent the mainstream. If Lux refuses to discuss the issue or to follow the talk page consensus, and continues to revert, he can be blocked; but hopefully, other editors will chime in and a consensus reached and followed. I'll watchlist the article, though I don't expect that I'll be contributing to the content per se.
