I'm not saying that but again, this book is written with specific politics in mind, and with real-life groups of people in mind too, this book and the writer of this book, advocates the murder, the genocide, of real-life people, sure he exaggerated them to all hell and back but that's the point, a lot of white supremacists tend to characterize and dehumanize people they don't like, and this writer is a white supremacist, not just a white supremacist but an extreme white supremacist at that, given he clearly states that the only way his supposed 'perfect' society can be created is the complete and total genocide of most of humanity... all real-life groups of people, IE not fictional at all.
Doesn't change the fact that it was a bad thing he did in the said writing, regardless of what the fans think. It's more about the writer's intent, George wanted to show how and Anakin became Vader, and that road was paved with terrible things born from anger. The same can not be said of the Turner Dairies, which the writer clearly intended to be a manifesto of his desired world and the manner in which he could active said goal.
