What is so bad about Meg Griffin?

Seconded, but playing along.

Meg Griffin is ugly as fuck.

I suppose I must disprove the theory that Meg's appearance can be considered ugly, for it has been stated multiple times in this thread, and it seems to be the general consensus by most characters on the show.
Upon searching for the term "ugly" in google images (with the safesearch option set to moderate, of course), the following image is made visible to us:

We must ask ourselves now, just what makes this individual hideous? One could point out her teeth, her inflamed gums, her lack of a nose, or her painted eyebrows. If anyone would like to contribute more, then it would only make my case stronger, so I encourage it.

Meg Griffin's appearance, as previously indicated, is this:

 Spoiler

Meg, unlike the woman defined as ugly, has straight teeth. Her gums are not seen as swollen. She has her mother's nose -- and her mother is seen as attractive by multiple characters in the show, and even some individuals on the internet -- and her eyebrows may not exist, but eyebrows are not drawn on any family guy characters, so in this light, any family guy character could be considered disgusting. By comparing Meg Griffin's appearance to an individual deemed universally hideous, it soon becomes clear that there is nothing outlandish about Meg's appearance. Even her figure is not disturbing, and in one episode a man comments approvingly of her ass. I will try to find the clip, but I am not promising anything.

edit: I found the video.
