Another point I forgot to respond to: "Jensen advocates repudiating "shame" (by his definition), but thinks that guilt should be encouraged in men to make them aware that they are committing wrong acts in using pornography or patronizing prostitutes, strippers, or other forms of sex work. Guilt, Jensen claims, will make men take responsibility for their attitudes towards women. This is Jensen's worst idea in a litany of bad ideas."
I really like that you emphasize the corrosive and counter-productive effects of guilt, because there's a big part of the political left that seems to be hooked into the idea that more guilt and self-denial is what is needed to tackle all manner of social problems. I think its this "hairshirt" streak of the left that goes a long way towards marginalizing progressive ideas.
I think this gets to the root of where Jensen is coming from, too – the fact that he's all about guilt is pretty apparent in his writings on race and on capitalism, as well. Most notably, he made a big to-do last year about his decision to join a church, in spite of his professed atheism. I don't think its any coincidence that the church he joined is a Calvinist one. Similarly, Hugo Schwyzer is also a socially conservative Christian (albeit, an Episcopalian), and John Stoltenberg holds a Masters of Divinity from Union Theological Seminary. This religious streak among male radical feminists really calls into question the idea that they're coming from an perspective that's fundamentally different from anti-porn activists from the religious right.
