Americans have increasingly taken a more liberal view on many of them since then. The latest reading, from a May 1-12 poll, shows that at least 60% of Americans find 10 of the behaviors to be morally acceptable. In addition to birth control (92%), alcohol use (79%), and divorce (77%), sex between unmarried men and women (71%), gambling (68%), smoking marijuana (65%), embryonic stem cell research (64%), having a baby outside of marriage (64%), gay or lesbian relations (63%) and the death penalty (60%) round out that list.
At the other end of the spectrum, there are seven behaviors that fewer than four in 10 Americans deem morally acceptable, including teenage sex (38%), pornography (37%), cloning animals (31%), polygamy (18%), suicide (17%), cloning humans (12%) and extramarital affairs (9%).
The issues that divide Americans most closely are buying and wearing clothing made of animal fur, doctor-assisted suicide, medical testing on animals and abortion. On each, the gap between “morally acceptable” and “morally wrong” views is less than 10 percentage points.
