No there won't be for the reasons I've just stated. It's ideological. There has always been a human rights lobby, Amnesty International etc who want the entire world to be modelled along the lines of Western European states
I think the anti AbuDhabi lobby falls into three categories:
1. Human rights campaigners. There are many in this group who are dissembling, using human rights issues to cloak baser real reasons. Many of them had never heard of AbuDhabi before the Sheik bought City and they did not campaign for human rights in the M.E. before.
There are, of course, some genuine campaigners as well as some liberals who seem to believe in a colonial model wanting to teach Arabs how to govern themselves, as you say, along western democratic lines.
2. Nationalistic Jews. Probably quite rare but there are some who are anti AbuDhabi simply because they are Muslims.
3. Outright racists who look down on people with brown skin. Some are just xenophobic others rabid. There is a pretence about being opposed to state ownership of clubs but they know really that City are not state owned but rather just reflect royal family influence. They didn’t think QE2’s horses were state owned, though.
None of these people will ever be convinced to change their minds.
I do not include as anti AbuDhabi people anti City fans called rags and so on. They are fine if they are genuine fans of other clubs and just prefer their own club to win rather than City.
US owners simply are pissed off that they cannot make the millions they expected since City hoover up so many prizes. They have resorted to trying to nobble City via the back door of the rules. They are almost as bad as the racists in pretending to have noble motives but with different motivation.
