I can understand the "bullying part" for sure, when I went in a Leafs jersey, I was mocked and insulted an incredible amount, but I never took it to heart or anything, it's just a part of being in an arena full of the other teams fans. (I can assume the insults go both ways though, I tend to go with friends who are a mix of the two teams, and we don't bother anyone else so I don't see as much bullying otherwise).
I think it's somewhat of a dumb article though, nothing really interesting hear, it's just a silly reporter jumping on the fact they don't want ticket holders shelling out, thus letting in possible unwantables and making for more sens oriented atmosphere).
Although I would also like to point out that Toronto's tickets are so damn expensive I can see why so many make the trip.
