Let's go with dangerous and unusual. Would you agree that both of those adjectives are entirely subjective? That your application of those terms would differ from the application by someone else? A schoolteacher at Robb Elementary School for example?Those are definitely things developed since the Bill of Rights was written so would be excluded based on the TeamD understanding of those rights.
I'd exclude them based on being dangerous and unusual, but not because they were invented after the Bill of Rights.
How about you? Would you exclude them for the TeamD reason, mine, some other, or would you say those are suitable militia weapons like battlefield .22's?
