You failed to mention that Beckham dove on his penalty kick ;)
C'mon, you know the truth...
Truth? This reader probably can't handle the truth that the Beckham PK was about as legitimate as Robbie Rogers going down so quickly in the box from a Klein bump. Both players were fouled, in my opinion, both lightly. Both made a meal of it.
But isn't that part of the game - to call the ref's attention and try to ensure a call? If Paulo Ferreira had gone down after the push by Ballack during the Portugal/Germany match, would the goal scored by Ballack have been called back for the foul? It was a definite push, but the ref missed it. He might not have if Ferreira had made the foul more obvious.
If there is no competitive advantage for playing through a foul, a player actually does his team a disservice by trying to do so instead of making sure the contact is seen. It's contingent on the ref to make calls accurately and consistently.
I reserve the term "diving" for non-contact flopping, complete pretending that a player was hit. I despise that. However, I take the exaggeration of actual fouls as something of a necessary evil, considering the game's structure. I'm also loath to judge how much a player is actually embellishing, because a kick on a knee or stepping on a player's foot may not look like much, but completely ruins a scoring chance and can, depending on the bone or nerve hit, hurt like hell. A stubbed toe can actually hurt more than a fractured wrist (I say this from experience, as I didn't realize for days my wrist was injured, but I know the moment I stub a toe).
I've gone over this with others before - and at least some of it seems cultural, as in some countries, playing through fouls is considered a badge of honor, while in others, provoking contact and calling attention to it is considered an art form. It's part of the game, however, just like coaches and fans will always defend their own - "Our star gets hacked mercilessly" while always looking skeptically at any player on another squad who goes down. That's soccer.
