Right I do agree with that a lot too.
I do agree that in general people look less favorably on heavy people - so they have a "strike against them".
But that being said, I agree with Jilly that people who are heavy often have poor self esteem and that causes just as much (if not more) damage. I know many heavy people who are in very happy relationships. So it can happen. It's all about the heavy person being happy with *themselves* and presenting that to the world. There will undoubtedly be someone who is drawn to that and who appreciates it.
It might not be easy - if you lived in a small town of 5,000 people and only met those people, maybe nobody in that group would be a good match. So it definitely takes work to get out there, to mingle with larger groups so you can run into those good matches.
