That, unfortunately, is a big part of the problem. That people believe this line of argument.
Taking this attitude, it logically results in the conclusion that the fans have no agency. That they are incapable of acting independently of the team.
My other team, whose games I am able to attend, haven't won a game since the middle of November. They were 2-0 down in 12 minutes at the weekend and that's how the game finished. The atmosphere, however, was still great. At no point did the fans stop singing/twirling scarves/waving flags, etc. It's fairly obvious evidence if any was needed, that the fans are able to make a decision on their own behaviour independently of how the team is performing.
Arguably, the only thing that we (as in Blades) can come out of this season with is that as fans, we don't give up. It doesn't require being delusional, just that irrespective of what is happening on the pitch, I am going to give my largely irrelevant all for the team. I'd say it is more impressive to see a set of fans continue to give their all when a team is down than because the team is 'sing-when-you're-winning performing well.
And then you get into the structural obstacles for individuals to take action without being told to sit-darn-shurrup and safe-standing in unassigned sectors is an obvious answer.
