To look at it this way you have to accept the premise that the song and video are somehow a 'self-parody'.
Well you and others seemed to believe him when he said that he was playing at degrading women and having fun with it, why don't you believe him now?
If you don't believe him, do you believe the model in the video? (link to the whole article is below, it's somewhat interesting)
So if there’s nothing “blurry” about about the male artist’s misogynistic intentions, what about the women involved in the project? The video’s female director, Diane Martel denies any sexist wrong-doing and dismissed Thicke’s comments in an interview with Eric Ducker at Grantland. Emily Ratajkowski, the brown-haired model in the video agrees. In an interview with Esquire, she explained that the women in the video were “directed to have a sort of confidence, a sarcastic attitude about the whole situation,” and that the “eye contact and that attitude really puts [them] in a power situation.”
The stunning model (who I wouldn’t recommend looking at unless you’re ready for a dramatic drop in your own self-esteem) makes an interesting point highlighting the complexity of this topic. She explains that growing up with a feminist mother made her realize that her body could be a source of pride. “It’s something very important for young women today to have that confidence. [The video] is actually celebrating women and their bodies.” So according to Ratajkowski, naked female bodies on television can be empowering. She also positions the video as a critique of the misogynistic music video genre. “Pop music is great, but there’s a lot of BS about the attitude of guys being super-gangster — that’s why the whole video is silly. It’s making fun of itself.”
