THe problem is not just on the opposition, it's the supporters, as well. If the supporters weren't so eager to give as much sh!t to the haters as they are to the game I don't think this woud stil be an issue. If people let the haters just be then after some time those people would've done one of two things which are ether gotten tired out after venting all their anger or moved on to other things. Instead, we got people fuiling their fire and keeping it going the same.
Alot of the hating is nothing more than children trowing tantrums, they are also quenched the same way, let it run it's course, and after a while the child would tire itself out and move on to other things. However, if the parent is just as childish then the situation scales and before long the situation has been escalated and prolongued beyond needed and things get worse than they were before.
So, to sumerize, I blame both supporters and haters.
