There was no reason for all the nasty comments. They were aimed at the fact that she was black and a large girl. It shows that they worship the shallow, outward things which I find not very attractive. Being dismissive of someone because of color and size is not conservative. Beauty fades but ugly inside is forever.
The negative comments were not because she is black. Accusing freepers of racism like that is an insult.
If this girl were white there would be twice as many negative comments. She is not beauty queen material in our culture. In other cultures she might be but in our culture we typically have thinner and taller gals with long hair.
