I gave you several footballing reasons though regarding Benitez. They are fair criticisms, and lots of them have been proven so. Especially the rotation in cups and the set piece defending. He wasn't an unknown, I was warning everyone how stubborn he was back when lots expected James to suddenly come back into the team. Weirdly, moving on James is one thing I did agree with.
It's very layered for lots of people, and people are all different. There are lots of reasons. To blame it all on people being upset with him being a red is totally wrong.
