So you're saying spectators (the non-participants) are only there for the atmosphere?
Who will be left? How about the people who are there for the soccer?
I think you are drastically simplifying the various categories of TFC fans. I don't think there are simply two camps.
I fit precisely into the group that doesn't chant. I'm not there to hear Red Patch Boys sing. I'm there for the sport. I'll always be there. People are not that simplistic.
If south enders are being priced out by $20 tickets, then I don't care. Businesses don't price products so that people on welfare or who have to support 4 kids on a single paycheque or who have low paying jobs can afford 4 seats to 22 games. If you cannot afford $20 a game then that's a problem for you, not TFC.
