The guy who have to show their guns in tight shirts...
They don't represent the entire faction, though. And that phenomenon isn't restricted to bodybuilding alone - you'll find tons of newbs / beginners / amateurs in any sport or activity doing similar stuff, like the punks who wear Tap out to show off their interest / "expertise" in MMA (or UFC or whatever it is) and shadowbox in the gym, the people who buy a whole range of needless accessories even before they start taking golfing lessons and so on. Those are the bad apples, giving the whole bunch a bad name / image.
As far as JNN's question goes, I'd say it depends on what the person wants - if someone gets some kind of satisfaction and fulfilment out of lifting and competing naturally (however you define 'natural', which is another topic altogether), no matter how crappy they look onstage, then so be it - at least they are not out there committing crimes or worse. If it makes them give up girls and what not, so what? Most people go through dry spells (including JNN himself, by his own admission), so they may as well do it for a reason that they think is noble or cool. As much fun as girls are, I wouldn't tailor my lifestyle and do or not do things depending solely on whether it will help me score or not.
I personally think it's a waste of time to compete naturally (no steroids, PH or hormones), esp. when you go up against people who juice, but if someone does it, it's no skin off my nose. People do severely underestimate the amount of muscle you can put on naturally - you'll never look anywhere close to a pro, but you can still look jacked enough to set you apart from 99.99% of the population. The problem is, it takes years and years of solid effort, with all the required accessories (diet, game plan, focus etc) on top of that elusive factor which is genetics, that a lot of guys give up after a few months and start juicing, believing that what they built in those few months or years is about as much as they can attain naturally. But as with juicing, naturals go through plateaus that can be broken through - it just takes a lot of time and effort, which most people don't want to invest.
