I don't see why we need to call anyone silly or be so defensive about this matter. Truth is , a lot of people value what they perceive as beauty , just as much as personality(like YokoKuwabara said).
And i don't see anything wrong with that. Maybe judging by looks alone can be a considered "shallow" but otherwise it's pretty normal to prefer a more aesthetically plasing partner.
Things aren't black and white. If you enjoy being with 500 pound , smelly gamers , that's fine. I think you should get off your moral high horse and stop judging people for not wanting to settle for someone whose looks they don't like.
