Nonsense. The US is a former British colony founded by English and Scots-Irish. Immigration has brought us nothing but cultural and classical Marxism and criminality. Just look at the Rust Belt and the liberal Northeast urban hellholes for the legacy of immigration.
And are you for legal immigration of Arab Wahabbists? Nigerian scam artists? Honduran gangbangers? When Bush and this Congress roll out the welcome mat that is what you are going to get. And they won't be coming here with copies of the Declaration in their pockets.
This nation is a nation of immigrants.
Now, a nation has a right to pick those they allow in their nation, but the Statue of Liberty is what Americanism is about.
What the other nations reject, send to us, and with hard work and desire, they will succeed.
The problem is not immigrants, the problem is welfare and multiculturalism.
