I completely understand, it's their equivalent of a professional foul, but what really sucks about the sport at that level (among several other things) is that the team sort of has no hope when they are down a man - Germany the other day is a prime example. But if they're the rules, than they are the the rules for everyone. Which really makes that sort of decision something only people who aren't real soccer fans can cry about. That said, Kewell had a cry about it
Recreationally soccer is okay, because there are little to no penalties no matter what you do (the only thing you would really penalise is a hand ball - below the elbow), but as a professional sport it sucks
