"Female sexuality is framed as something which exists for the pleasure of men" is a true statement in general media.
So. [Most] Porn. Watch it. Who's orgasm is displayed? Who's orgasm is typically non-existent (to the point it is fetishized when it does occur?) Make a judgment. Why is this true? See my earlier post about "bisexual porn."
Ok. Advertising. "With 'female sexuality' I thought about what arouses women." Good. That's a part of what sexuality is but not what it is framed as in terms of its portrayal in media. "You want that car because supposedly it helps you get the woman, it seems to be more about pleasing women than men?" I kinda hope you don't mean that. :) How in the world does 'getting a woman' as a heterosexual man 'please women?' If you are thinking about answering that question... don't!
It would be pleasing to women if their needs (sexual needs in terms of porn, practical needs in terms of cars) were met in media. However, only the needs of men (getting women somehow in BOTH cases) are being portrayed. That's a problem to men because it reduces us to gullible sex drives, yet it is worse for women because it reduces them to objects of that drive... dismissing any quality that a woman can have as an individual.
This is an example of the objectification you see discussed here. Women are the object, men are the subject, we see this in porn, advertisement, and even employment posters (gee, we wonder why 52% of women drop out of the programming field after college.) It's kinda gross and defeating when you take the "red pill" and start to see it everywhere. Even more daunting when you go against the grain of prevailing thought and start talking about this being an actual problem. It just seems like everybody else took the "blue pill" and just don't want to see it. But it does have a negative effect that has been thoroughly studied.
If we accept these tenets as true, and I do and will strongly suggest that you do as well, then we have to see the attack here as sexist. The attack serves to objectify in the same manner as media: by removing individuality, quality, and self from the person. It uses the sexualized images of women just as media uses for this purpose. It is done against a woman, who as I've discussed are oppressed as opposed to men who are simply (at most) discriminated against. It was done so in an obviously malicious manner (that is, beyond parody) in order to hurt their reputation by targeting the fact that they are female (given the nature of their attack,) not by aspects of their character or refuting the merit of their knowledge. That serves to oppress via discrimination determined by their gender: sexist.
