- I just don't notice people visually, or, visual elements are irrelevant to who I find attractive, so this question isn't relevant for me.
- Attraction is natural/innate/instinctive/mysterious, and therefore not under our control, so trying to influence it is a waste of time.
- Yes, it's a problem that we're culturally conditioned to devalue certain bodies, and we should try to deprogram ourselves (and here are some suggestions on how to do so).
For #1, I mean, sure, you may well be turned on entirely by intelligence, or personality -- I can completely believe that. I'd even say it's almost entirely true for me, for the people I've wanted to have sex with in the past, that I was much more turned on by their personality than by anything physical about them. But that said, attraction is a broader issue than that. It factors into whose features please us when we meet them, whose appearance we note is socially approved of. Some of that's probably biology -- a LOT of it is social conditioning. And I think it's tremendously difficult to escape that social conditioning, and that it influences everything from friendships to work relationships to hiring and firing, etc. So yes, maybe you're someone who can completely discount that influence, but if so, I have to think that you're a very rare bird indeed. Most of us react to other human beings' appearance, including not just weight, but also skin color, symmetric facial features, mode of dress, etc.
And #2 I think is missing the point that while some element of attaction is biological, a tremendous amount of it is culturally conditioned. Which suggests that if we've been programmed to react this way, it may be at least possible to deprogram ourselves, to some extent. And to try to help the next generation avoid that initial programming as much as possible. I'm thinking about banning fashion magazines from our house, for example. I wonder what Kavi will think of that!
