If I was the owner of Everton (or any other club) I would absolutely 100% not appoint Benitez (or whoever a rival manager for said club is) because it would be incredibly bad for business. Genuinely it would be the last thing I would do. People keep saying football is a business, well its not a normal business. If I am running a supermarket it doesn't matter if the customers hate me or not because they would not know me. Customers do not protest in other businesses normally. (I don't class Favre as a risk to be honest)
Again, you are not the issue here. Good for you for not being ruled by emotion, are you going to be controlling the thousands of people who will be ruled by emotion though? This is the part where any argument for Benitez falls flat on its face. Nothing else matters, a large amount of fans do not like him and never will, that's it. Tactics, winning stuff, small club jibe, past it, etc etc etc, none of it matters if the fans don't like him.
I am sure he is a lovely fella in real life. Again though its irrelevant.
