Why do people hate A-Rod so much?

Because not only is he a proven stereroid user, but all he cares about is money and he cheats to win (oh, and he's a total spaz). All you have to do is take a look at his previous visits to Toronto. Once he was caught at a strip club, once he yelled stuff out to distract the infielders on an infield pop up making him completely unsportsmanlike, and another time he almost cleared the benches after he charged the mound for getting hit with a mistake pitch (not at all intentional).
