I feel like a whole generation of kids are missing out on positive male role models.
Step up, and pass on the good vibes and knowledge
I feel like what a child needs is some sort of close-knit community to interact with daily, not just parents. It could be the extended family, it could be the neighbors, etc. This is how children grew up for most of the history of our species, hell, I'd guess most mothers throughout history didn't know who the father is at all. The idea that a child is raised exclusively by the parents is an extremely novel invention forced upon us by western individualist culture.
Genders or "parental figures" don't actually matter here, what matters is interacting with different people, forming personal relationships with them and learning from their positive traits and behaviors.
