Pew asked (pdf) citizens of 39 countries, “Should society accept homosexuality?” Max Fisher mapped the results:

It’s not even close. While there’s wide variation in places like Latin America and Europe, Africa is almost uniformly anti-gay. Nigeria is the only surveyed country where just one percent say society should accept homosexuality; 98 percent said society shouldn’t. Results are under 10 percent for almost the entire continent, including sub-Saharan Africa and North Africa, which has closer cultural ties to the Middle East. The important exception is South Africa, famous for its gay rights movement, where a still-low 32 percent answered “yes.”

Muslim-majority countries tended to reject homosexuality, with results under 10 percent for Islamic societies from Africa to Southeast Asia to the Middle East. The only exception is Lebanon, although the country is only about two-thirds Muslim. Only 2 percent of Pakistanis and Tunisians – who are generally considered cosmopolitan by Mideast standards – said society should accept gays.

To be clear, though, some Christian-majority countries also overwhelmingly say that society shouldn’t accept homosexuality: Ghana and Uganda, both in sub-Saharan Africa.
