Hard choice but I went with "women don't like porn"
Speaking as a woman who watches and has made porn, it's a ridiculous notion to begin with. Porn isn't all men, so obviously some women had to like it to be a part of it. I'm not too private with my collection and guy friends have found it and gasped and all I can do is laugh. It's just ridiculous.
Also, most women who are AGAINST porn just haven't found THEIR porn. I just read an awesome article about a feminist who decided to stop going after porn that objectified women and made ones where the woman's satisfaction was of top priority. She went on to start making porn where it was real, just real sex and love making between people of all sexual orientations (although I suppose asexual should be left out of that general statement)
