It is of course just wrong. The idea that immigration runs counter to the idea of America is breathtakingly ignorant of the very history of this country.
While this may be true, I do think it's important to add that for a very long time large amounts of Americans have been more in favor immigration as an idea, rather than a policy.
What Americans have been and are still interested in is what power our Government has in controlling Immigration.
SCOTUS said in 1893
every sovereign nation has the power, as inherent in sovereignty, and essential to self-preservation, to forbid the entrance of foreigners within its dominions.’” That principle was upheld this year by the Court in ruling in favor of the Trump Travel Ban.
Obviously we can allow others to join our country but we have the sovereign right to specify the terms and qualifications. We said, in the Declaration of Independence, that
Americans are absolved from perpetual allegiance to the British Crown To
no individual can be ruled without his consent.So any immigration policy based on charity, compassion, or trite phrases like “ diversity is our strength” is ridiculous.
We have the duty to insist that those wishing to join us will adopt our habits, manners, independence, and self-reliance.
Plus present useful skills to prevent them from becoming victims of the welfare state.
