I don't think Roissy claims women want to be objectified. He agrees with the majority opinion that they like to be treated like human beings, appreciated for the qualities particular to them as individuals etc.

He just adds the coda that giving women what they like is a very poor strategy for sleeping with as many of them as possible, as quickly as possible*. Roissy doesn't really care what women want except insofar as knowing it furthers his aims, so this doesn't create a great deal of cognitive dissonance for him.

It was in fact reading him that inspired me to write this comment yesterday.

*In fact, he claims it makes women disdain you and calls it "supplication". The Roissy way is never explain, never apologise.
