I can't really speak to pornography as it actually exists in its mainstream (male-produced, male-consumed) incarnations, which is what Jensen ultimately cares to talk about, so I don't have a dog in the race (and I suspect he's right about a lot of things), but--yeah, he fits way too many of the stereotypes of the anti-porn crusader (the ghost of Andrea Dworkin lives on, God bless her soul) for anyone on my flist to be really comfortable with his argument, I think, even despite the fact he's not really talking to any of us.
