every fan-boy/girl is a stupid moron. Point blank. It's not their company, it's not their console, it's not their games. It's just consumer merchandise they personally preferred to buy over something else. And then they feel the need for whatever reason to validate their choices to themselves by ranting and raving about them. Unless you actually work for Sony or Microsoft or Nintendo, you have no real reason to try and profess the greatness of one over the other except personal taste and opinion, which aren't truly valid reasons.
Just like all the people that get excited over sports teams screaming "WE WON!" or "WE LOST!!!". No you didn't; the team did. You just watched them do it.
