Bitter much? The Aussies are upset because Phelps defeated their home team in every event, so once his 12,000 calorie-a-day diet was revealed, they weren't shying away from making crude comments and insults.
They're just like the Americans when they lose--they whine, complain, find scapegoats, and throw hissy fits like spoiled children...which isn't far from the truth. No wonder they can't fathom going through China's athletic or academic programs--it'd require too much effort in addition to assuming responsibility and blame for one's own actions. They'll blame it on the oppressive Communist regime, of course.
Phelps practices in the pool every single day for several hours, swimming for a few dozen kilometers. If I am not mistaken, a swimmer of his caliber isn't exactly going to do a leisurely swim in the community pool as his daily practice. He most likely does other forms of exercise, such as weightlifting, to increase muscle strength. He is obviously not a "lardass"...and calling him by that shows incredible immaturity.
Assume that Aussie swimmers have the same rigorous training regimen as Phelps and eat the same amount of calories every day as he does--it can't be that different. Would you call them lardasses, then, or is that reserved for the Americans (because we obviously are all fat tubs of lard)? He's not an attention whore because he doesn't try to draw attention to himself, but because his accomplishments draw others' attention to him. He's not an egotistical maniac, and even if he were, his actions would back up his claims.
Come on, you people are not children. Show some restraint and maturity, especially on the Internet. Phelps isn't going to be hurt by your invectives because he knows things you don't and never will.
