Arguments about authoritative definitions tend not to be interesting, but I think that the claim is that using physical characteristics as judgment points leads to "insufficient regard for a person's personality or sentience" and that that insufficient regard is not limited to one sex.
Hopefully this at least clarifies the point I was trying to make and addresses a little of the "you too" that you're feeling. Perhaps not, we'll see if this thread persists.
Anyway, your point is still wrong. Judging someone as not sexually attractive is pretty much the opposite of sexual objectification, it's a refusal to treat the person as a sexual object. I might be perfectly willing to have a relationship with fat bald guy as a cOlleague, or as a tennis partner, or as a friend - I'm not denying his humanity, I just don't want to sleep with him. Compare that with his action of rubbing himself against me, even after having made it abundantly clear to him that I wasn't interested. He doesn't care about me and my wishes, they are irrelevant to his goal. He finds me sexually attractive, and he wants to get laid, and too bad for me if I don't agree.
So no, refusing to see someone as a sexual object is sexual objectification in the same way that not collecting stamps is a hobby.
I think this sort of boils down to a misunderstanding between those who want to be seen as more than physical characteristics and the desire not to have unwanted physical interaction. I think those are both valid desires. The unpleasant experiences both "sides" have had make this discussion difficult. A failure to recognize you as a person with desires that aren't in accordance with someone else's projection onto you is clearly very bad. I don't think rejection is at this same level of very bad action, but it is still substantially hurtful to many men. You could just say "so what" to that and I'm not saying it to imply an obligation to accept. I'm just saying that it hurts to be rejected. Hopefully that makes some sense.
So no, rejecting someone as a sexual partner is not sexual objectification, pretty much by definition.
Specifically, sexual objectification is when you see someone as nothing other than a sexual object - they have no other characteristics in your eyes. Now, knowing that, I would like you to explain to me how making the judgement that someone is not attractive is in any way shape or form sexual objectification...
