Singapore has seen “distinct shifts” in attitudes to gay rights in the last five years, with support for same-sex marriage rising, a survey released on Thursday showed. Nearly six in 10 of those aged between 18 and 25 believe same-sex marriage is not wrong, according to the survey by the Institute of Policy Studies, a Singapore-based think-tank. Although the island remains socially conservative, the poll of 4,015 Singaporeans found opposition to gay marriage had fallen to 60 percent, down from 74 percent when it was last conducted in 2013. “Overall, Singaporeans remain fairly conservative in their outlook, though there have been distinct shifts on issues surrounding homosexual rights,” the Institute said.
