Promoting sustainable fertility is good in my books. We need sustainable fertility like we need sustainable environmentalism, and similar things.
I strongly believe that low fertility causes immigration backlash because some governments try to maintain their population by importing immigrants rather than fixing the fertility issue and a low fertility causes the domestic population to be insecure (e.g. "replacement theory") in the face of the immigrants. Some immigration combined with sustainable fertility is the solution.
