You mention the problem of not having two role models, but why stop there? For so much of human history kids were raised by whole extended families or clans even. I think the real issue today is the absence of that sort of extended community in people's day-to-day lives so we seek it out online. This isn't so much of a problem in religious communities. In the rural US the Christian conservatives are still doing fine getting married, having kids, and supporting each other financially. The church to this day provides a lot of people with this sort of community. I'm not advocating for Christian conservatism by any means, but there's something to be said for how they manage to maintain a sense of community in the modern day. For the rest of us we're kind of at a loss of where to turn I think. Some catalyst is needed for people to organize a community around, but I'm not sure what a good catalyst might be if not religion
