But surely you realize the ultimate contradiction in your statement - if TALL people only hang out with other TALL people or OVERWEIGHT people with other OVERWEIGHT people or SMALL people with other SMALL people --- where are all the small people for YOU to be hanging out with?

You're arguments are strewn with gaping defects in logic (someone tell me the Star Trek episode in which that is said and i'll award 2 points). I think you realize this and despite all the explanations and justifications i think this is really, ultimately, a self esteem issue. You're entitled to opinions - as are we - but what would be the point in sounding off here if you weren't looking for some kind of support and or advice? If you have great traits, which no one is denying, then don't let a lack of confidence in yourself destroy your best chances at a social life. See a therapist, work on the issues as much as you feel you can yourself, and everyone here will be rooting for you. All the best.
