Thomas Jefferson's Warnings on Today's Leftist Immigration Policies

The following quotes from Thomas Jefferson are from a website I'm not familiar with, titled The Progressive Conservative, which to my mind is a wacko oxymoron. To describe a political position, the term "progressive" was consciously chosen as a way to obscure the Communist agenda it was intended to represent. There must be a huge number of people who identify with it today who have no idea what they are supporting. What on earth it means on this website I don't know. I'm reproducing part of this article because I appreciate its point of view. And by the way, they also quote Jefferson saying some things about immigration that the Left would embrace, but since they go on to counter it with the following I didn't quote that part. It's there if you want to look it up.

In his Notes on the State of Virginia (1787), Jefferson reflects:

"It is for the happiness of those united in society to harmonize as much as possi- ble in matters which they must of necessity transact together. Civil government being the sole object of forming societies, its administration must be conducted by common consent. "Every species of government has its specific principles. Ours perhaps are more peculiar than those of any other in the universe. It is a composition of the freest principles of the English Constitution, with others derived from natural right and natural reason. To these nothing can be more opposed than the maxims of abso- lute monarchies. Yet from such we are to expect the greatest number of emi- grants." (3)

Jefferson warns, nearly prophetically:

"They will bring with them the principles of the governments they leave, imbibed in their early youth; or, if able to throw them off, it will be in exchange for an un- bounded licentiousness, passing, as is usual, from one extreme to another. It would be a miracle were they to stop precisely at the point of temperate liberty. These principles, with their language, they will transmit to their children. In pro- portion to their numbers, they will share with us the legislation. They will infuse into it their spirit, warp and bias its directions, and render it a heterogeneous, in- coherent, distracted mass.
