Anecdotally I see perceptions that we're continually after managers being sacked (yes, Cooper, but also dissatisfaction with Maresca last season). And that we boo our own players, e.g. Ward.
As mentioned by others, fans are drawing from limited experiences like highlights and when we play at their ground. Personally I don't think we are entitled - in fact most of our fan base has been not entitled enough to force the change we needed to kick on.
Also the poverty chanting, our clappers and goal music. All of which is shite and needs to be binned.
