This author does blame the politicians (the Kennedys, Johnson, etc.). Who can blame immigrants for wanting to bail their 3rd world hellholes and come to the greatest nation that ever was?
Do you disagree with the following (from the essay)?: "new arrivals [from 3rd world nations] make no effort to assimilate; to do so would be "genocidal," a notion that makes a mockery of real genocides. Instead, long-forgotten grudges are nursed against the white populace. Native citizens take to flight as the neighborhoods around them, the norms in their hometowns, are debased for the convenience of low-paid immigrants and well-heeled businessmen. All the while, indigenous paychecks drop through lower wages and higher taxes collected to provide social services for immigrants. And this only takes into account legal immigration. These results were unforeseen by liberals easily led about by their emotions."
The only part of the above paragraph I disagree with is his blanket statement about "new arrivals." I would amend it by saying "the majority of new arrivals."
There's a lot I disagree with. It's a lot of broadbrushing.
