If there is a man who believes, in an innocent sort of a way, that women are equal and treats individual women as equals in his eyes (I think that there are many men like this) then I think that such a man can watch porn and find that doing so doesn't conflict with his ideas that women are equal. Because he doesn't know of, isn't interested in or doesn't understand the political analysis that underpins feminism.
Clearly this hypothetical man is blind to his privilege that enables him to reconcile a belief in women's humanity with an enjoyment of porn.
With regards to what you said here Buffy, yes he is blind to his privilege but he is also guilty of 'othering' women.
And, for a lot of men, there will be double othering going on. The reconciling can only happen within a cultural framework of othering women as the sex class, and with certain women forming the (doubly othered) subgroup of the porn sex class. We see exactly this sort of attitude with prostitution (which is not surprising given that as I said earlier, porn is simply filmed prostitution).
If you asked the average male porn consumer if they would be happy with the idea of their wife/girlfriend/mother/sister/etc being in porn, they would say no. If you asked them how they would feel about themselves being treated like women are treated in porn they probably wouldn't even have a proper understanding of what they were being asked.
It is just plain old fashioned woman as other + madonna/whore complex. Which is clearly illustrated in the etymology of the word pornography.
