To be fair to him, he retracted that statement (Not that he actually commented on whether or not his beliefs have changed as a result of reading the linked research).
Now, I remember that you said something along the lines of "I am not influenced by advertisement" earlier, Lorric. The thing is, I completely believe that you believe it when you say that. That does not actually mean it is true, because even though it is easy to say "I make this commercial decision on the basis of rational fact", actually doing that is near impossible. The second you make an impulsive buy, even one you rationalize later, the second you just do something on a whim, that's where advertisement has shaped your decision making in some way. Even the complete rejection of anything that is actually advertised is still a reaction to advertisement.
Economic theory is full of examples how we aren't rational actors in that space. Assuming us to be capable of being rational actors in any other field of human endeavour is a folly. We can, occasionally and with great effort, act rational. Most of the time, we're just following our impulses and try to rationalize them after the fact.
You may ask what this little excursion has to do with feminism and the issues we're talking about here. Just as it is easy to spot the big shouty advertisements, it is easy to spot big, overt ways in which women are made to be less than men, and thus very easy to avoid those, to make statements to combat these great ills, and then be happy and secure in the knowledge that you did your part for the greater cause of equality.
But this concentration on the big issues lets all the smaller ways in which inequality harms us slip away. By allowing the existence of these little jokes, we subconsciously accept the picture of women they convey. By dismissing an opinion we do not like by saying "Well, s/he just needs to get laid", or by saying things like "This isn't a woman's/a man's job", we restrict the way we're accepting people.
That, more or less, is why I am such a fervent supporter of Ms Sarkeesians' efforts. That is why I criticize you for only referring to her as "Anita". By denying her even the most basic of courtesies, you belittle this person in a way she does not deserve.
