One can argue reasonable restrictions all day long on the 2A (and we do amongst ourselves) but pre-marxism I'll guarantee that there wasn't one American who would have for an instant honestly thought of the 2A as a collective right. If the court rules 2A as a collective right, and a democrat gets in the white house while dems control any house in congress, the true tyranny will begin because "the people" are the same throughout the consitution. If this one goes the others will follow.
I do honestly believe that the scholars arguing this as a collective right are either disingenuous or lacking certain critical thinking skills. It is absolutely clear from the founding documents, the grammatical devices in use at the time, the writings of the founding fathers and practices in this country pre-War of Northern Aggression, that the intent, purpose and underlying rationale of the 2A was as an individual right. Anyone who believes differently is either intellectually dishonest, intellectually ignorant and mentally defective. It is only by making the "breathing, living document" argument like a good leftist that any hint of collectivism gets introduced.
Unfortunately for them, this nation was founded on individual freedoms, individual expression, and individual rights granted every person by God and protected by the United State Constitution. I just hope the liberals on SCOTUS are intellectually honest enough and clear minded enough to rule on this with their minds and not with their emotions and agendas as they usually do.
