It's a slippery slope. 

Via Fox: 

The startling new proposal by 97-year-old former Supreme Court Associate Justice John Paul Stevens calling for the repeal of the Second Amendment to our Constitution’s Bill of Rights is unwise, dangerous and totally unrealistic. For 227 years, the amendment has guaranteed that “the right of the People to keep and bear arms, shall not be infringed.” We should not abandon it.  

The first 10 amendments to the Constitution make up the Bill of Rights. These amendments are the foundation of our liberty and the lasting legacy of the Founding Fathers who so wisely created a Constitution designed to protect the freedom of generations far into the future. These rights are a major factor in what makes America an exceptional nation and a beacon for freedom that attracts people from the world over.

Once we begin whittling away at one of our rights in the Bill of Rights, what’s to stop the erosion of the others? Freedom of speech? Freedom of religion? Changes like this wouldn’t be minor tinkering – they would amount to major disfigurement of America’s foundational document, equivalent to amputating a person’s arm or leg...

The idea that we should correct an absence of responsibility by the few through empowering government to strip rights from the many is more medieval than modern – a license to lawlessness, not a defense of legal and moral rights.

The hidden argument in Stevens’ pitch is this: An individual’s sacred right to self-defense, to the defense of innocents and against government, boldly embodied in the Second Amendment, is transferable to government.

Alas, life of a free citizen is hard. It is not about repealing rights, but about learning to use our God-given, constitutionally protected freedoms responsibly. That is why the retired Supreme Court justice is wrong. The fault is not in the Bill of Rights, but in ourselves.
