Why do so many women put themselves down?

I read everyone profile, look at everyones photos that they are willing to share.

Here is what I find. That many of women on here say that their ugly or what have you.

From what I have see. You women are beautiful I have no idea where you get that your unpleasant to the eyes.

I just want to state that all of you are very pretty and you all should be told that more often.
