I buy into everything you say about Mansour's personal responsibility being- shall we say - a matter of dispute. But to summarize the UAE's human rights abuses as making homosexuality illegal is leaving out a lot.Mansour is Deputy PM of the UAE, where homosexuality is a capital offence. Whether the facts that Mansour was not the one who implemented this policy, that his religion demands it and that he would quite conceivably be lynch-mobbed to death if he were to propose changing said law are relevant or not depends on your viewpoint.
Flogging and stoning are regular criminal punishments, freedoms of association, speech, and religion are non-existant. Labor, women's and children's rights are severely curtailed. Apostasy is punishable by death. And so on. Wikipedia entry
And if you don't trust Wikipedia, just search for UAE human rights abuses. It's not the world's worst, and they are careful to treat foreign visitors well. But behind the pretty facade is a nasty place.
The comparison by someone else above of this to Phil Anschutz is preposterous.
