They should have never been brought into this country in the first place. They have no business here.
The Official Immigration Policies of the United States are taken from various issues of the National Geographic magazine of the late '40s and early '50s. That is, the quaint and colorful Kodachromed natives in those articles are your new neighbors and the new voter base of the Democrat Party. E.G., See the Bolivian Market Lady wearing four derby hats! Meet the Somali slave dealer!
Read the articles and you'll learn about their fascinating cultures based on Islam, polygamy, slavery, camel, goat, and sheep rustling and intertribal raids. BTW, the modern National Geographic is sickening in its political correctness!
Now, Americans ... such as they are ... no longer need travel to exotic climes or read National Geographic. Just go down main street and make a left at Martin Luther King Boulevard.
