I'll give it to frostz there, colonization & immigration are two different things, & I agree with you, unless you're an American born or naturalized citizen, you shouldn't take a role in government. But in my last post, I'm referring to the immigration of the ancestors of the people that now today say things such as get out of the US if you don't know English. The extremely ignorant person that made this topic, most likely has someone in their ancestry that once was a non-speaking immigrant living in the US. If someone was to tell that to their lets say great-grandfather, that person will be offended so there's no reason why they should be saying it to others. They have to view things from other perspectives.
indeed, many people living in the United States including whites, have some immigrant ancestry. I personally count anyone who came after the establishment of the United States an immigrant. Everyone before that were colonizers.
While it may be unfair, the United States does not exactly have a friendly policy towards immigration, for those who they see as non-white. This whole discussion, is intricately tied with racial issues, even though I don't think anyone had actually brought it into the discussion.
This discrimination against immigrants in the United States included eastern europeans, and "colored" people from other countries. From the standpoint of American culture, it is perfectly acceptable to discriminate against immigrants, particularly against the undesirables such as the Irish (who were white, but were seen as black), and many others as well.
The only acceptable immigrants were from Western European nations such as Britain and these would never face the barriers that others would face in the country.
The only reason why such discrimination is no longer done at least openly is because of the ethnic social movements that have been going on for the past 50-60 years or so.
