Yeah I see where you are coming from. On the other side of the coin though there are some fans who get so disgusted by our results that they actually avoid watching. I don't think that makes them any less of a fan. I honestly think it's just a difference of personality.
However the reaction to our last few seasons have been disappointing to me. There is a large portion of the fan base who are very spoiled. Always being in the top 4 and being somewhat competitive with other top sides, and in seasons further removed actually winning the league, has created a kind of entitled atmosphere in a lot of the fan base.
