Do you agree with the Native that argument that supports immigrants should not be allowed in the US?
I understand the Nativist point of view and can follow their arguments. However, I have to go against it, in the final analysis. I think that the Nativist position was articulated out of fear. This fear of the dialectical other and general fear towards change is diametrically opposed to the courageous ideals of American society. Whether it was Jefferson writing The Declaration of Independence, or the Patriots who stood against the British at Lexington and Concord, or the soldiers who endured harsh winters and conditions at Valley Forge or crossing the Delaware River, America was not a nation born out of fear and mistrust. The Nativist position justifies their antipathy towards immigrants out of sentiments of fear- fear of the nation falling apart, fear of there being a lack of job, fear of the loss of culture. I think that in a globalized setting, one cannot cling to fear because the rapid spread and sharing of information and communication is making our world relatively "smaller." Such a paradigm does not make room for fear. The Nativist position does not seem to speak to such a modern condition. Even in the times ranging from the mid 19th Century, when Nativism first appeared in America as a movement in the North, it seemed as if the Nativist philosophy was carved out of fear and mistrust, elements that deny the essence of American identity.
This question is not very clearly worded, so I'm not sure what you are really asking, but I'll give it a shot.
First of all, I don't agree that immigration should be completely closed off. Legal immigration provides us with a lot of motivated people who come here and contribute to our economy in many ways. Also, bringing people in from other countries contributes to our ability as a people to identify with and understand the viewpoints of other countries.
However, it is also easy to see the downsides of immigration. A homogeneous society is one that can be more cohesive. When we all speak the same language and have the same culture, it is easier for us to identify with one another. Having a melting pot society makes for more social tension than we would otherwise have.
