I would like to see quantifiable evidence for it, because then it starts to beg the question "Do we censor?".

To me, this is just about being an educated consumer.
Just like when you have to think of the many children who were caught up and killed in Colombian warfare for your weed, you have to think of the many abuses women go through in porn...
[and yes, more than men, admitted by the men themselves. You don't need men to verify that though. Just look at the mechanics of the female body, they will naturally go through more damage given the nature of the work because its a physically delicate place].
Or hell, pollution from gas companies or a corrupt bank. You wouldn't keep a corrupt politician in office, would ya? [Well, maybe that's a whole other topic]
All in all, there are many industries that need better regulation out there...As well as consumers who are willing to think about what they are buying or consuming.

Men naturally objectify from a biological standpoint, and porn exploits that natural urge to the point of absurdity. Porn geared towards women's urges must be sought specially. I can't tell you how many times I've been with a man, and he would have sex with me like he had gotten tips from porn all his life. Every women is different. We don't all like to be pounded, but some of us do, and we don't all like to be degraded, but some of us do! Porn is intended to be a means to and end, not a sex manual or the freaking karma sutra.

I guess it just surprises me that porn still attracts people or turns them on in light of how fake and tacky it can be. Except this kind of "fake" is worse than other forms of similarly tacky entertainment [WWF, soap operas], because its giving an already repressed society the wrong idea of what sex is, which reaps a much more emotionally damaging result.
...More than you would ever get from reading a comic book.

Conversely, I feel the same way about Disney or Twilight type movies giving the wrong idea about what love is suppose to be.
