Currently the battle is about preventing foreigners from having their children becoming American citizens. But the 14th Amendment is about much more than that. It is part of the Reconstruction Amendments that were created after the Civil War. They are three of them, and according to Wikipedia: “The Thirteenth Amendment (both proposed and ratified in 1865) abolished slavery. The Fourteenth Amendment (proposed in 1866 and ratified in 1868) included a redefinition of citizenship, the Privileges or Immunities Clause, Due Process and Equal Protection Clauses. The Fifteenth Amendment, (proposed in 1869 and ratified in 1870) grants voting rights regardless of “race, color, or previous condition of servitude”.
I find it mindboggling that anyone in the United States, especially anyone who knows the history of these amendments, would think of changing them. But read about them and decide for yourself.
