Might I ask why we must have such a useless thread? I personally refuse to "objectify" women based off of their hair color. For all I care, a women could be bald, I'm fine with it.
If society basis what someone looks like off of who they want to be with, regardless of the time, then we have a messed up society. What matters is on the inside, not on the outside. If you're apart of the percentage who judges based on looks, then you are the shallow. Now-a-days, all these model things are all just money-grabbing schemes, no one will ever look like how they portray the "perfect" person as. Has history taught us nothing?
Don't give me some religious reply to this comment, unless you can find me a region which exclusively states you must judge based on appearance (no not some made-up one that you want to create).
TL;DR: Picking between a blonde or a brunette is stupid, idiotic, and I don't support it.
