A simple enough question: How many children should people have?
Do you feel, to any degree, that there should there be a limit for any reason? If so, in what way? How should it be enforced - with laws, an honor system, or something else? Is it someone's right to have children? If so, can someone lose that right in some way? What ways? Do concerns of overpopulation (the idea that there are too many people for the world to handle) or eugenics (people of "good breeding" having kids together and/or preventing people with "bad" genetics from having children) influence how you feel one way or the other?
Answer as few or as many questions as you like. (b'')b
