Well by calling Gail Dines Mary Whitehouse Mark II you've immediately ensured you lack credibility. MW was a right wing moralist, GD is a feminist. Accusing anti-porn feminists of being moralistic, anti sex, anti enjoyment, is a very well-worn man-pleasing tactic. Hey look at me, I'm one of the cool girls, not like those pearl clutchers over there. It's only works if the people you're talking to are impressed by shit like that.
Google porn (without the filters). It is the most popular search engine on the web and it works by showing a list of sites in order of popularity. Have a look at what the most popular stuff is. See how many misogynist, violent, sexist sites you need to wade through, before you come to the liberated empowerfulising stuff. Good luck with that, see you in five years.
