Question: Isn't mandated child support basically just welfare for needy children? What is the moral difference between compelling parents to support their children and compelling all people to support the needy in society? Many critics of the welfare state believe that parents should be compelled to support their children with basic levels of physical sustenance and education, such that failing to provide these constitutes violating children's rights. But how is that different from compelling people to support other needy or vulnerable people? Is the blood relationship what creates the obligation to support the child – and if so, how?

Question: What is the proper role of government in adoption, if any? Many religious people recoil at the notion of gay marriage due to its implications for adoption. They fear that the government will then allow gay couples to adopt on a broader scale. I suspect that the government is taking too great a role in adoption, and that's what causes this particular controversy. So what role should the government play in adoption? Should it screen parents and forbid some people from adopting? More broadly, what would adoption look like in a free society?

Question: Do adopted people have a right to know who their biological parents are? Some adopted people want to know their biological parents, and knowing one's family medical history could be important to a person. So does a person have a right to know his biological parents? If so, does that apply to children conceived with sperm or egg donors? Do parents giving children up for adoption or donating reproductive tissue have a right to privacy?

Question: Why do you think that giving a child up for adoption can be "problematic"? Why wouldn't adoption be preferable to abortion in most cases? (This question is a follow-up to the discussion in the 23 January 2011 webcast about children as an optional value.)
