Umm...it's actually called human nature. A happened and B did. Happens all over the earth. Can't remember the Cowboys being booed on GF day 2015, maybe that's by chance or maybe it's just because they're not a pack of grubby merkins.
You have made a good point here. Melbourne fans are as bad as their team. Having to suffer them all week saying 'all the haterz want Billy banned because they're butthurt and aren't real league fans' (massive irony on the last part), it's now so sweet that the butthurt is now firmly purple-based. And when the Storm stink it up in the future, whenever it happens, they'll find a new sport to go to. The drop-off in support will be palpable.
Munster's act on Manu perfectly summed up who Melbourne are. Arrogant, grubby, unprofessional merkins who sook it up when they lose and perform dog acts like that.
