I think that was Bobby McFerrin. But easy mistake to make
In answer to the bulk of your post, I doubt fans will ever be happy (for any team, anywhere) unless they win. I am willing to bet if you went over to the Laker boards as their team was beaten in the finals, there were plenty of "Player X sucks" and "We need to get rid of Player Y". Never mind the fact that this particular group of players had won the Western Conference, and taken them to the NBA Finals.
Sports fans en masse are fickle. The Boston fans who were calling for Doc Rivers' and Danny Ainge's respective heads 18 months ago now proclaim them to be legends.
I like to think that in general I can be fairly objective about Orlando - I love my team, and I was immensely proud of how they did last season. I realise that they have a way to go and I want them to take those steps, and realise it may take a couple of seasons of development for Dwight, who is the key to our success, and a few offseason moves before that happens. But it doesn't mean I won't get caught up in the emotion of any particular moment, over-reacting to the perceived success or failure of any game or offseason acquisition, etc. Sport is an emotive endeavour, particularly for the fans. Logical thought is not always going to happen. I think if you asked every Magic fan to give their honest assessment on the team, specifically their progress from the season they bottomed at 21-61, they would generally be quite happy, and expect they upward trend to continue. But ask them their opinion during a game when we are getting blown out on our home court by Minnesota and yo will get wildly different responses.
