Brings up an interesting question about what "supporting your team" actually means.
If it means just turning up for every game, questioning very little and going with the tide, then by all means have a good time but understand that you are part of the problem.
If it means wanting the best for your club, not wanting it to be denied progress by a flood of B teams, and not supporting a competition that's an obvious back door for that scenario, then the most supportive thing to do is denounce, undermine and boycott.
