The U.S. needs to lower immigration for many reasons.
First, the United States is the most racist nation ever in the history of mankind. Why would we ever take people from their own countries (where there can't be racism, since they are in the majority), and place them here, where they and their children will suffer racism for the rest of their lives? This racist white establishment will cause immigrants to drop out of school, get pregnant, not marry, take drugs, etc. The racist police will arrest them and the racist judges will throw them in prison. It is immoral to make people suffer like this. Second, the white man stole land from native Americans. If we are to give them back their land, then step number one is obviously to stop immigration. Every immigrant is someone who is preventing native Americans, this country's original inhabitants, from using their land and their resources. Third, the average U. S. citizen causes more greenhouse gas emissions than anyone else in the world. Imigration will cause there to be more American citizens, and will therefore cause global warming.
So if you like racism, dislike native Americans, and like global warming, then feel free to promote an increase in immigration, as well as illegal immigration.
