And admit it, you judge people by appearance, we all do. Just people disagree over what makes a person attractive, taste varies. For every man you find who like's em skinny you'll find one who doesn't. Same with blondes and brunettes, short people, tall people, the list goes on.
If you like who you are and the way you look it doesn't matter, however there are a lot of people with image insecurities, you just have to either accept the way you look or change it.
