Polls are responded to only by those with an interest or an agenda and quite easy to manipulate. Having said this it matters not a jot whether other fans like Chelsea or hate them, I would be upset if anyone hated me without meeting me purely for my affiliations.
the media is mostly responsible for adverse feelings towards the various clubs. Throw in some consecutive wins, personal issues, the odd owner, the odd manager and a few villain players and hey presto. If people dislike Chelsea because of money, it's fake morality. If people disliked United because they won so much, its misplaced feelings at personal failure their clubs failure or some other failing. For me I really disliked Fergie and I can't stomach anything good said about Giggs. Those were\are my two United dislikes, the club its self, couldn't give a monkeys. As for Chelsea, just the owner, the rest I couldn't care about So this most hated in the land things is bollox. It ain't one single aspect that can simply be measured by asking people who do they dislike most, far too simplistic.
