The KC Royals have a decently long history of many good players, multiple championships, and irritating fans beyond reason. There are those fans who are always looking on the bright side, then the complete opposite who only see the bad, and in the middle are fans who can see both the good and the bad.
There are likely also some outliers in between these groups, but the point…all types of fans are important. Without diversity among the fanbase, nobody would be seeing the light at the end, or nobody would be asking the difficult questions and pointing out when the team is making questionable moves.
