When the president takes the oath to preserve, protect and defend the Constitution, I'm sure he also means that he will do everything within his power to keep all hands off!
Some people want to change the Constitution, and those who will wave in our faces when they feel their rights are being violated or challenged. I may not like some of their rights, but I will defend them. Many Americans have died protecting our rights.
The Second Amendment gives us the right to bear arms. Some do not like it and want to change that right; we must defend and uphold it. The Constitution is what made America the greatest country in the world.
