It's still very close, but there has been a modest shift in the view of Americans overall towards the status of gay relationships, whether or not we should have legal protections, and whether or not we should marry. As you would expect, the seat of anti-GLBT sentiment is older people, religious conservatives, Republicans, and southerners.
Data here and here. When I have a chance, I'll look at some of the breakdown numbers more closely, but here are the big ones:
The biggest is that for the first time, the number of Americans who think GLBT relationships can be "moral" exceeds 50%.
"Moral". It's an odd term, and an odd concept. Would we be more moral if we were married? Isn't that a catch 22?
This one strikes me, it's all over the chart, whether we should be legal or not. This is the "civil unions + marriage" group. And isn't it odd more people consider that we should be legal, than consider us "moral"?
This one is basically a flat line. We are making slow, if agonizing, progress on the other two issues. But this one seems intransigent, overall, even though we know that state by state we are improving. Not sure why that's the case.
