Mr. Duke is no leftist Lurker, I can tell you that. I’ve been reading his stuff for a while and he’s hard to peg. But if I had to describe him I’d say he’s a bit like Joe Sobran. He’s ardently pro-life, anti-immigration (he even opposes legal immigration) and extremely traditional in terms of sexual mores. He’s also never boring, whether you agree with him or nor.
He may claim not to be one, many leftists do. That doesn't make it so.
