Why Not Just Push for Legal Immigration?

In a few years, we are going to be a majority brown country. White people will not be the majority in the country any more. His will be the first generation ever in american history in which whites will be a minority. This is all about what they call demographic destiny. On me too. I don't deny that. Why not just push for legal emigration? If you were genuinely concerned about bringing people to the united states, you know the poem, right? Give us your tired, your poor, your hungry, right?"
