I had two children at that point, too. It’s what happens over the next 15 years that really affects your national demographics
We’re getting more and more apparently muslim refugees in my area of Florida. It really is a surprise to go shopping and see a big family of 5+ kids seemingly all under like 8 years old. Not something you would see much before this, LOL.
Cubans used to have children. So did American rednecks. Natives like the Seminoles.
If it’s only Moslems having large families, then that’s it. I know a priest from Jamaica, a few years older than I am (maybe 60), who is one of 12 children of his mother. He tells American mothers with large families, “Keep it up, keep it up! Don’t let the Moslems win!”
