Y'all got to forgive my blondeness. I've never done this!
Cultural significance, that terminology is the whole axis on which this question is balanced. Since the significance spoken of is described in a myriad of ways, this question bears great debate. First off cultural can apply to educational, artistic, enlightening, enriching, intellectual, social, or ethnic. Educational can imply, not only a sense of learning, but enriching through that learning, and focus on knowledge. This focus on knowledge would enlighten, making clear, and opening social boundaries. Therein lays the concept, and the responsibility, personally, of the second amendment.
This amendment was included within our constitution and it most likely addressed Americans have the right to own fire arms for personal protection against threats of crime, the right to hunt game, and jurisdictions have a right to have National Guards or citizen defensive forces. Note that with this last reason the guards are national and the defenses belong to citizens. This, in itself, denotes a unity, a similarity, a spirit of community. Citizenry is that group assembled under a singular alliance. This is crucial to the application of the second amendment. No waging differences of religious zealotry, racial separation, or ethnic difference. All the staples and application of the second amendment weigh entirely on the unity of community. The commonness which binds us, that of being American, with the acceptance and understanding of our differences, is the key to why the second amendment has the means to work. I have no idea where this quote originates, but it sums up the crucial, critical, learned acceptance of difference, and its application within the second amendment, “I may disagree with what you say; but as your fellow American I defend, to the death, your right to say it.” America, the world’s melting pot, where your words are your own, as long as they are not spoken with cause to incite.
