There are two questions looking into the motives of the NRA. The second is mine, focusing on the motives that would be assigned by the opposition. The first focuses the "real motives" of the NRA, quoted as:
I wanted to know what the real motivation behind the NRA is. Is it driven by a true belief in the second amendment or are there financial motives also, something similar to the big tobacco lobby for example?
It might come down to how this question is parsed. In how it reads, emphasis applied, this question aims towards the actual motives of the NRA; attempting to attribute motives to the NRA, short of crawling into the heads of the board, runs the risk of being very subjective, applying the bias of the writer and demonstrating opinions.
However, if the question is parsed as "Is it driven by a true belief in the second amendment or are there financial motives also?" that leaves to much room for the question to be closed as "Primary-opinion Based." As a distinction, my question allows for the citation of what those who oppose the NRA claim about them, allowing for the political realities of the situation.
