From IBTP, go read the whole whole thing.
Convincing women that they are being unreasonable, that dudely porn use is natural, normal, and even necessary-for-his-health behavior, and therefore you should support his porn use, and by the way you’ll never even find a dude who doesn’t use porn — this one of the most successful misogynist campaigns of the modern megatheocorporatocracy.
The truth is that if you’re with a guy who uses porn, you’re with a guy who at his core believes that women are subhuman fucktoilets.
Women never want to believe this, for about 386 reasons. The idea of being objectified by the entire ruling class of default humans is too awful to contemplate. The implications are unthinkable. Women disdain to consider that life under the auspices of a culture of domination inexorably taints all relationships. But mostly they just don’t want to have to confront the porn-usin’ dude they love, the dude who will think they are being unreasonable, the dude they know will dump them before he’ll give up his porn.

Better still – read Loving to Survive by Dee L. Graham et al because these authors provide astute analysis and insight into how male supremacist system and men constantly claim they alone are capable of defining women’s reality, from the male myopic perspective of course. So naturally men’s views of ‘truth’ are the definitive ones are they not?
If women were to eavesdrop on male only conversations they would be horrified at learning just how much men hate and/or hold women in contempt. But far better to adopt the three wise monkeys views: hear no evil (hear no male domination over women); see no evil (see no male domination over women); speak no evil (refuse to name men and male supremacist system as the problem).
