I really don’t care if this country is minority white. There was a time when articles like this were written about Northern Europeans vs. Southern Europeans or Nordics vs. Russians and Jews. At one point the Germans were going to destroy the country that was populated by the English. And, of course, for decades it was argued that letting the Irish in was akin to letting rabid wolves loose on a flock of unprotected lambs. When an article like this is written, its not about blacks - their share of the population has remained surprisingly steady. Its about Latinos and, to a lesser extent, Asians. Personally, I would have no problem if Latinos and Asians migrated legally if we had a system that taught US values to them. Those are the two pillars that are necessary - legal migration and teaching US values. Opening the floodgates to illegals and Woke values will destroy the country.
In other words, your solution to illegal immigration is to legalize nearly all immigration. That's like solving the problem of shop-lifting by de-criminalizing or legalizing petty theft.
It doesn't matter if millions of Meso-American peasants and slum dwellers come here legally or illegally, the net result will be the same - America will look like a Mexican or Guatemalan slum. I'm not sure what measures could be take to prevent this by "teaching US values" - putting them in a classroom to stare at pictures of George Washington won't change anything.
