The south did not believe in liberty and justice, rather believed in slavery, and inflicted it on blacks, and on whites who were coerced to guard what they were told was their betters’ slaves.
The National Rifle Association was created to assure black freedmen could have firearms with which to defend themselves from the Klan. The cowards of the Klan preferred to rape and murder the unarmed. The NRA limited their preferences.
That is your opinion. Here is the fact from the Constitution:
We, the people of the Confederate States, each State acting in its sovereign and independent character, in order to form a permanent federal government, establish justice, insure domestic tranquillity, and secure the blessings of liberty to ourselves and our posterity invoking the favor and guidance of Almighty God do ordain and establish this Constitution for the Confederate States of America.
