Farrocks- no one is saying that the ONLY thing that matters is weight, only that weight matters (to many). Being that there are many, many, good girls who don’t have a weight problem, a sane person will choose a girl that is best for him. Because there are far fewer blonde girls, that makes it far more likely that a boy would have to sacrifice ANOTHER important quality, to get his blonde. That would likely be shallow.
You can’t honestly say that a boy who is attracted to blondes, and chooses a blonde over a non-blonde with all other thing equal is shallow. He is wise, and sane. To do otherwise would be insane. It would be like choosing 99 dollars over 100.
It is sad for many girls, especially those with no fault involved. Just like it is sad that there are poor, ugly, sick, and handicapped girls. But shallow? Try sane.
