Maybe this is part of what upsets the right wing folks when childless people are concerned about the welfare of kids.
You're not supposed to worry about "other people's kids" (otherwise known as human beings with their own rights).
At BEST you're only supposed to worry about your kids, but even then, you're supposed to worry about competing for things, not their fucking well-being as individuals.
You're not supposed to look at a child & see a person. You're supposed to see property*.
