For example - I knew a guy that was like 450 lbs. Poor schmo was a social pariah on most levels...women wouldn't go out with him...etc. Sure he had his friends, but what real consolation is that when you know that every relationship in your life is predestined to be nothing but platonic?
So finally this poor guy at around 35 or so decided he wanted to finally lose his virginity - and he went off to the only place he could - some brothel out in Vegas. Well, without meaning to get too much into detail, things didn't work cuz he was nervous (I guess), the girl tried too hard out of frustration (I guess), and ended up injuring the guy. He spent the next day in the hospital getting some things attended to.
That guy's entire situation was a consequence of his weight... He was a virgin because of his weight. He was in the hospital as a consequence of his weight. Everyone knew it - but nobody would say anything to him. Instead - my friends offered him platitudes about how people were "so superficial" and "someday he'd find someone that recognized his inner beauty" blah blah. Ya know - they said all the things that we accept that we're supposed to say - even though we know it ain't in the slightest bit true.
I remember talking to one of my other buddies right after the hospital incident and asking "Do you really believe the nonsense that's spilling out of your mouth about how he'll find someone, someday, that looks past it?" His response was "Maybe he'll find a fat girl" (in other words - someone that's in no place to judge and therefore will settle). Then I asked "So you don't believe it, and you're not being honest?"
"It's not my job to be honest with him. It's my job to make him feel better."
...and that - I think - is the underlying problem. NOBODY is honest. Rather - everyone walks around playing these weird games about trying to obfuscate the issue in order to be "nice" - because not being "nice" is the ultimate sin.
So - yeah - it's a pretty messed up situation IMHO for fat people. Their friends mis-represent the world to them, tell them that the only thing that might motivate them is actually "selling out", send them off to fight battles we know they're not going to win (because it makes us feel good about ourselves to do so), and confuse them with vague nonsense about the concept of being "fat" in and of itself.
