I support the whole of the Second Amendment, just like I support the whole of the First Amendment.
You must look at the entire amendment.
“A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms shall not be infringed.”
Sometimes the “well regulated Militia” part gets glossed over in favor of "shall not be infringed." We need to take into account the entire statement and recognize how things have changed since it was written.
For one thing, the British knew Americans were planning to revolt, so they demanded that suspected revolutionaries turn over their weapons. Our Founders knew that a time might come when the “security of a free state” might be infringed. After all, our fledgling nation had enemies on all sides and protecting our United States might prove necessary.
For another, the weapons of 1776 are far different from those we have today - muskets and pistols would be no match for an AR-15. Just as laws have changed with the advent of trains, planes and automobiles, laws should reflect improvements in weaponry. Something as simple as registration and background checks can keep weapons out of the hands of those who would do harm to our families, communities, and nation.
Despite what some fear-mongers have proclaimed, no one is coming for your guns! No one is taking away your right to defend your family or your country! Certainly not me. But I do believe that putting fair restrictions on what I call "weapons of family destruction" will keep our citizens safe.
