It's nothing unexpected, but the historical polling data on gay rights is fun to look at. In 1977, Americans wanted gay people to have equal rights in employment by a 56-33 margin. By now, the lead has risen to 89-9. In 1982, the margin against considering homosexuality an "acceptable alternative lifestyle" was 34-51. (The phrase "alternative lifestyle" has always struck me as a bizarre way to describe homosexuality -- is my preference for women of very fair skin also an "alternative lifestyle"?) Now things have swung the other way, and 54% are accepting of homosexuality while only 41% are not.
Take a look at these very comprehensive numbers from Pew as well. From 1999 to 2006, support for allowing gay people to marry, adopt, and serve in the military has increased substantially. As you'd expect, support is strongest among young people. The 18-29 age group supports adoption by a 58-38 margin and military service by a 72-23 margin. As people think about the issue and open-minded kids grow to voting age, we win.
