This was WFB's conclusion in that epic issue of NR (it was Joe Sobran he determined to be truly anti-semetic). However, I think his tendency to be controversial where this topic is concerned stems as much from a compulsion to stick his thumb in his critics eyes. And of course make a few bucks in the process.
Too bad 'cause he undermines his own positions on other topics where his powers of persuation might do some good.
Where does he say Hitler was misunderstood. He said he was an anti-semite. There is nothing wrong with trying to understand history, and looking around the ‘official version’ often leads to new insights.
