I both don't believe that the white population is being replaced, and even if it was, I don't care. I am not a racist, my family tree does not resemble a circle.

Issues of migration and fertility rate are related to structural incentives and constraints, level of urbanization, economic development, etc.

I want my country to prosper. It won't prosper by closing itself off to migration. I hope it attracts more researches and highly educated people from around the world, especially now that the US is shunning them.
