Or, as I have heard from multiple friends who have chosen not to or can't have children(due to ethical concerns or lack of money), they understand completely and expect that parents take responsibility for the commitments they made without pushing the problems onto everyone else.
Not to mention that having children sits at the very base of human existence. We built societies around the plain fact that children are necessary. Only those who believe that humanity should just go extinct can argue that having children is just a personal choice.
