Is it unfair for Utah fans to hate Derek Fisher because he left?

It is completely unfair because Fisher had a choice to either receive treatment for his daughter's cancerous eye in New York, Cleveland, and Los Angeles. He picked the city that he was the most familiar with, he's been there since LA drafted him, and the big thing is that he didn't leave utah to be in a better position to win because at that time utah was much better than LA. The season before, I believe we were exited from the first round of the playoffs from the suns, and utah was in the semi-finals. It wasn't until bynum began to develop (which nobody predicted he would progress so quickly) and the mid-season pau gasol trade (which was triggered because of bynum's injury). Fisher was more comfortable in LA, than he would have been in cleveland or New York, and also he left a lot of money on the table when he left utah, i believe utah saved like 21 million from letting fisher go, and they should be happy that they ddin't have that contract in their books because fisher has been regressing over the years and would have been vastly overpaid under that past contract. The most important reason, was that left utah for family reasons, and almost every fan booing him there would do the same for their own family. The fan reaction towards fisher has been unfair but it's gotten to the point where it has become too personal. The fans are wearing shirts saying "fisher lies," some are wearing patches on their eyes to make fun of his daughters eye, just personal attacks that no deserves. Honestly, I have lost complete respect for utah fans, and they just continue to embarr not only themselves but the nba as well.
