When I read their forum, they remind me of people losing trust in democracy. They don't realize how harmful their views are, which in part is probably because they don't believe them to the hilt. It's posing and tribalism, mostly.
However, just like in any functioning democracy, the losing side has to admit defeat. It's pivotal, because to not do so is playing with fire. If you don't believe you can win an election, why run at all? The answer is you don't. And in democracy, you will try to find other ways of reaching the power you feel you've been cheated out of. We might see an excellent example of this soon across the pond, but that's another story.
However, it's similar to what the fans on Bluemoon are posting now. If you genuinely believe you won't be allowed to win the league, that it's genuinely rigged against the team you support, then why watch it at all? Again, the answer is that you won't.
But these thougths, ideas and debates are gaining ground and I find it worrying. I don't enjoy for one bit when fans of our own team talk about referees being biased against us, implying that it's rigged against us, because should they ever convince me, I'll lose the game I love. Because my love, and I'm sure it's the same for all of us, is absolutely dependent on the core belief that we have a fighting chance.
They don't realize quite yet what they're doing to their love for the sport, and ultimately the sport itself. If we don't accept defeat, ultimately there can't be a winner. And just like in a rigged election, there'll be no point in running at all. They still care, so they still don't truly believe in the shit they spout. But they're getting there.
