Upvoted for your interest not in the debate itself but the best articles to cover both sides.

So instead I am going to say there is not just one reason for my extreme bias toward advocating for guns to be available to anyone. However, there are some very real and valuable pieces of information that give you an idea of why I will likely never change my stance:

The above article is about Democide and is very worth the read. In a few words it talks about how countries with very few (effective) checks and balances are far more likely to go to war and also to murder their own "subjects". It talks about this being so because the elites of those countries are willing to murder their own countrymen and allies. So they use their ample resources as a show of force to steer the society into following their propaganda.

In light of this, I will show you a foundational social psych study that shows pretty well what % of people will follow immoral orders:

Important quote to take away from this article: "Results-- Some teachers refused to continue with the shocks early on, despite urging from the experimenter. This is the type of response Milgram expected as the norm. But Milgram was shocked to find those who questioned authority were in the minority. Sixty-five percent (65%) of the teachers were willing to progress to the maximum voltage level. "

Just an interesting point to add---this study was done in part to assess how German soldiers could be led to follow such orders as those required to perform the duties required of them during the holocaust.
Here is a quote from wikipedia about it as a matter of fact:
"The experiments began in July 1961, in the basement of Linsly-Chittenden Hall at Yale University,[3] three months after the start of the trial of German Nazi war criminal Adolf Eichmann in Jerusalem. Milgram devised his psychological study to answer the popular question at that particular time: "Could it be that Eichmann and his million accomplices in the Holocaust were just following orders? Could we call them all accomplices?"[4] The experiments have been repeated many times in the following years with consistent results within differing societies, although not with the same percentages around the globe.[5]"

Once you understand human nature within the frame of history, it becomes very difficult to advocate for the disempowerment (at any level) of one another...
