Our government including this President gives actual machine guns and anti-aircraft and anti-armor missiles (and grenades, mines, rockets, artillery, armored vehicles, training, etc.) to citizens of other countries in hopes those citizens will overthrow their tyrannical governments or otherwise kill the people we don't like (or can't profit from).  Many of these "freedom fighters" also happen to be radical islamic terrorists.  Then those radical islamic terrorists migrate here, legally, illegally, refugeegally.  Then they mass-murder Americans.  Then our government and this President (and his chosen replacement) want to ban and confiscate arms from law abiding American citizens.  Inquiring minds may wonder why this would be. Why would we want to take away the rights from and disarm law abiding citizens while simultaneously arming those that wish to come here and kill law abiding American citizens, and even invite them in with open arms?
