If there exists an academic paper regarding an analysis of contemporary opinion concerning the National Rifle Association, it is obscure to non-existent. Probably, the latter.
Academia does not seem interested in the topic. However, the general public has high interest in the topic, as evidenced by the person who posed the question, and by the large number of opinionated webpages focused on it.
Much can be gleaned by what partisans have written, as well as, what they omit, or bend to fit pre-existing conclusions. For example, the left-wing, posing as apolitical, SNOPES website, wouldn't outright state the gossip about only Democrats being mass shooters is false. They would only say that there were instances when it could not be proven to be entirely true.
Only by the greatest gymnastic stretch of bending facts could anything approximating NRA membership be attached to a mass murderer, since the founding of the NRA, in 1871.
So, str-e-t-c-h they did! The State of Connecticut requires a certificate be obtained from the NRA, in order to purchase a firearm, legally. The alleged shooter in Newton, CT had such a certificate. However, he was not an NRA member.
While on the subject of stretching to meet an agenda goal, the murderer of President McKinley, Charles J. Guiteau, a psychotic, said he killed the President to help the Republican Party meet its goals. That ought to be sufficient evidence that all Republicans are potential murderers.
