Statement (1) is likely correct. Massive wealth and leisure tend to encourage "softness" and the entirety of world history is there to bear that out.
Statement (2) I see very little evidence for. In fact, as societies become more and more "egalitarian", like the Norse countries, we see women gravitating even more to "female pursuits." Additionally, in our own country we are seeing an increasing rejection of rationality in favor of emotionalism. Masculine, that is not.
Regarding women becoming more masculine maybe you are correct. There was an old order or traditional way of behaving that was considered feminine. In reality, like chivalry, it wasn’t entirely biologically innate but part of our culture that emphasized the most feminine aspects of women that are innate. Emphasis on the good and beautiful if you will.
Now when I interact with women who have been raised outside of that way they often come off as course, vulgar and acting like one of the guys. They are of course still female and if you “forget” they are a woman and start treating them like one of the guys you will be called out eventually.
Oddly, there is often still an expectation that men will act with chivalry even though it has become more typical that women have abandoned their part of that arrangement.
All that to say, I guess I agree with you. Women are still feminine in that they still view the world as women do, through the feminine perspective. What I’m seeing is just a rejection of a culture that emphasized that which was considered the best and most beautiful about women. Just as chivalry and acting noble was an attempt to emphasize what was best and desirable in a man.
