I understand why someone would not want to date someone else who is grossly overweight...but judging someone by their weight alone IS shallow and shows a great lack of character.
There are plenty of normal weight women out there...and many with a whole host of problems worse than some extra weight on their frame. Be my guest and have at it. I'm sure you'll get exactly what you deserve.
BTW...I know a gentleman who felt the same way you do. He used to even tease his sisters, nother and other girls about their weight whenever he could. He thought it was hysterical to do this. Then he met the love of his life....she's a lovely woman who fights with a physical condition that keeps her weight way over what she would like. They have a wonderful marriage, two healthy, beautiful children and he wouldn't trade her for spome hot babe in a bikini for anything.
