Or, if you prefer, address my point about the structure of that sentence: "being necessary" embellishes the point. It does not set a condition, it merely explains why the right exists. If it were to be intended to set a condition on the right to bear arms it might say "for those belonging to a militia," or, "in times when the security of the nation is threatened." So you have displayed here your ignorance of history and your inability to understand English. Pretty good start, newbie!
