Uhhhh.......anecdotally my mostly male friend group is rapidly approaching our 30s and exactly 1 of us is married, and it isn't one of the liberal ones.
The more liberal ones are having more sex, probably even more than the guy with 2 kids, but I also know for several of them the long term goal is to actually raise a family, and it isn't clear their politics has done them any favors on that end.
At the end of the day though, I don't see any of them becoming good church going boys just to find a good church going girl to have kids with. That's a thing my dad did in the 70s that lead to me, but I'm not convinced it made anyone involved in the process particularly happy. I'm also an aesexual though so maybe I just don't have the genetic desperation everyone else has to draw context from.
