IMO, you should still show up and sing for the players on the field, this is after all, your club.
The only way to fix things is to have Red Bull sell, so all protest and measures should be directed towards that goal. That means:
*Get rid of season ticket, attend on a game by game basis
*Do NOT introduce new friends/fans to RB games
*Do NOT buy anything at the stadium
*Do NOT purchase any merchandise anywhere
*All TIFO should be directed towards #RedBullOut or #SellTheTeam or no TIFO should be made at all
*Contact the marketing departments of RBNY business partners and let them know that you will not support their business as long as they're associated with Red Bull
I'm still holding out hope that Dyer's source was wrong and this is all a sham. They have been moving in the right direction in terms of fan interaction the last couple of years. This would annul that progress.
