Not surprising, and not something that really bothers me.
Two interesting things that jumped out to me that don't really fit some of the connecting narritives to this...
Abortion is still under 50%. And the only "liberal" moral notion that actually seemed to DECREASE was wearing fur. More people find that to be morally acceptable now (though only 1%) than before. It's the only "liberal" notion that actually went away from the liberal direction on it.
I also feel like this is...somewhat...missing the point on some of these.
To me, some of them aren't necessarily "moral" or "immoral" choices. I don't find divorce "immoral". I don't find having a child outside of wedlock as "immoral". At the same time, I see these as things society as a whole should essentially discourage and urge people to make choices NOT to run into a situation where it is needed. To me there is a difference between saying something is "immoral" and saying something is generally a "negative" thing.
Divorce, as a concept, is negative for example. It's something that, as a society, we should strive not to have in a hypothetical world. Not because people are trapped in unhappy marriages, but rather because people should be in happy ones. Now naturally, that's impossible to achieve, and thus I divorce is necessary and I don't feel like it's "immoral" to get one. But in a general sense, you'd like to see less than more of this.
I'm happy to see doctor assisted suicide over 50%.
Definitely interesting to see how things continue to progress, especially politically as you get new crops of people coming off age. I said in another thread, I still think there's room for social conservatism within politics in the next decade, but the direction, method, and message needs to change. It needs to become a notion that's less about policies and more about perception and personal responsability.
