Pew Issues Global Morality Survey
issued a report on a "global morality survey" they conducted last spring. As you can see above, homosexuality averaged out to be somewhat more acceptable than adultery and gambling in the 40 countries surveyed. In the USA:
An overwhelming majority of Americans said extramarital affairs were morally unacceptable. But fewer Americans said that abortion was unacceptable (49%), with 17% saying abortion was morally acceptable and 23% saying it was not a moral issue. Meanwhile, less than four-in-ten Americans are strongly opposed to homosexuality (37% unacceptable), premarital sex (30%), gambling (24%), divorce (22%) and alcohol usage (16%). For these issues, a majority of Americans said that they were either morally acceptable or not a moral issue. And when it came to the issue of contraceptive use, only 7% said this was unacceptable.There's an interactive chart on the homosexuality question. The "acceptable" responses seem rather low, especially for the United States and Canada. The shaded percentage column below is "unacceptable." Hit the link for the full list of countries. The top five surveyed nations most accepting of homosexuality: Czech Republic, Spain, Germany, Argentina, Chile.
