Anecdotal evidence, just my experience. I was thinking about this, because personally, in my relationships as a single guy, I'm seeing a different trend.
I get the vibe from women, the ones I've dated, as well as platonic friends, that strong personality/traditional masculine traits, are more desired than I can remember.
One specific story: I had a romantic friend from London meet me in New Orleans for a short trip. I took control, booked flights and hotel, and made a bunch of dinner reservations, etc. When we were there I made it clear if this restaurant or that place wasn't her favorite, we could always change plans. It occurred to me she had little say in what we did. She was happy with everything, the interesting part was that she was bragging to her friend on the phone that she didn't have to do anything, I handled everything.
I was surprised it was that big a deal, and asked her about it. She made it clear that she and her friends have discussed at great length how tired they were of wishy washy men, can't make a decision, can't take control, etc. New York City, the same thing, women complain about video-game playing layabouts. I'm not seeing a desire among the liberal east coast women I deal with to date a bunch of weak-chinned vegans.
There might be less men's men these days, but that just makes them more valuable.
