I think the human mind is capable of compartmentzling objectification when it's appropriate and humanization when it's not. We just have to teach it to do so via introducing more non-sexualized human bodies in our day to day life.

You look at those who have grown up in nudist communities - or regular European beach life - and you'll see they can already do it quite well. Or at least much better than the average North American.

Of course it takes time, as with any change. But as these other cultures show it's more than possible if there's a will to do so.
