OfCourse, you said: “Ive always wondered why the heavier girls are more discriminated against in the frum community, and less able to find husbands, than the world at large. Or am I wrong?”
I believe that you are wrong. Larger girls are discriminated against even more in the secular, Conservative and Reform communities as well. From what I have seen and been told, this issue is the same in all religions and all walks of life. It is so unfortunate that many men cannot see beyond the fact that someone is not a size 0. They miss out on wonderful opportunities to meet women who are clever, witty and wonderful prospective wives and mothers.
