Why all the hate?

I know there is animosity towards the Miami HEAT but its gotten ridicules.  There are face book pages and websites dedicated to hating the HEAT, and more specifically, Lebron James. 

I understand the people of Cleveland being upset, but why everyone else?  If he would have gone to the Knicks I would hate him.  But I hate every Knicks player.  If he’d gone somewhere else I would have been disappointed, but not hate the team any more or less.  I just don’t understand.

Furthermore, considering many sports are just “bandwagon Jumpers’, I’ll bet as soon as we start winning this hate will turn into love.  And they’ll swear they were HEAT fans all along.
