I am a little late on this rant, but I felt it needed to be done. Michael Phelps raced a shark and people are angry it wasn't a real shark but a CGI shark. Of course it was. Did you really think that Phelps was going to get into the water with a real shark?
More importantly, the people who feel their anger over this is justified are the same people telling you not to discuss politics because its pointless. This is the place we have come to in this country, we get angry over discussing political or social issues with real world impact, but we feel justified in getting angry an olympian didn't get eaten by a shark.
