Why? It's completely true.
Dictionary definition of misplaced ire.
From the very start, there's been a notable section of support who have been desperate to jump on Benitez and were outright disappointed Everton were winning games early on. It's just a sad fact. I get it, I'm not foolish enough to have not expected it, but it's incredibly childish.
There is a large portion of the support who refuse to allow the slightest bit of criticism to fall on the shoulders of a manager who has 1 win in 9, and 2 points from 18.
This division was inevitable with the appointment. People feel humiliated watching their own team. People are acting like they are of higher moral standing by supporting this failing manager, but it's a ridiculous position to take and one that will look really silly.
