Regarding the discussion about "answers", remember to play chess and not checkers.
The RKBA is a philosophical argument, not a policy argument. Gun control folks want to argue policy, and want to do it with absolutely no proof of efficacy of any of it.
So, first, make sure you understand the philosophical foundation of why the right to keep and bear arms exists, and why it is protected in the Bill of Rights. Understand that it is rooted in the right to life, and the logical derivation of the right to self defense to protect life and property under assault.
Understand further what the philosophical purpose of government is. Philosophy determines the purpose of government, and in a free liberal democracy the purpose of government is to protect individual rights to life, liberty and property. Remember that people have rights and governments have powers that are granted to them by the people. It isn't the government's purpose to take care of people like a parent.
Remember that living in a free society means that individuals are free to think, do, say, and possess whatever they please so long as it does not infringe on the natural, constitutional, or derived civil rights of other humans. Again, it isn't the purpose of government to tell us what we can and cannot do outside their basic charter.
