According to the passage ,the leader of World Bank ,Jim Kim wants to improve the gay rights .Due to this fact, he used the bank as a kind of political tools ,which would baffle the development of economy . There three main reasons: First, it seems capricious. Uganda is hardly the only country with anti-gay laws on the books; nor is it the only one to have recently toughened its anti-gay stance.Second, the stress on gay rights itself seems arbitrary. Of the many forms of bigotry the bank could battle, it is not clear that anti-gay laws are the most harmful to the poor. Third, his approach is likely to backfire.
