Nice sweeping generalisation you have there, care to make a few more? I wasn't there so I wouldn't really know, but if there is a bit of noise in hte SCG, you can't hear the ump, not even hte whistleNo the boos started after a mark wasn't paid to Pyke with a minute to go. Crowd was too stupid to know what the touched rule was.
They then picked up the boos again once the siren went and continued on during the Dogs celebration.
Not racists (even though we have Aboriginal players including Brett Goodes) just a bunch of sore losers who don't understand the rules of the game.
