Having children is good. Children are the animating force of society. Whitney Houston sang all about it. Without children, we don’t have a species. All indisputable.
But not having children is also good. Some people don’t want to be parents, some people shouldn’t be parents. Some people want children but, for whatever reasons, do not. Some have fewer children than they would like because they fear they cannot afford more, and some people have more children than they necessarily planned because they don’t know how to use a rubber.
Regardless, whether somebody has children or doesn’t have children isn’t a reflection of their values, their patriotism, or their commitment to the nation.
