I have no problem with owning a gun to defend yourself or for sport shooting. However, the idea of individuals arming themselves to prevent oppression by the government is not rational.
In Wounded Knee, S.D., or Waco, Texas, resistance to government was unsuccessful.
On a larger scale, Native Americans attempted to defend the areas where they lived and their homes. They were unable to achieve that goal and the federal government relegated them reservations. They had guns. Timothy McVeigh and some civilian militias felt oppressed and the Oklahoma City bombing was a result. The Civil War was the Southern states' reaction to oppression and tyranny. They were unsuccessful. More than a million Americans died.
