all species defend themselves by various methods, but by and large they don't use weapons -- that is strictly a human invention. The use of weapons allows the "pecking order" to be artificially manipulated, and "stand your ground" laws become a form of legal vigilantism (read murder). The pro-gun arguments put forward by the average gun nut are all based on rationalizing their paranoid anti-social behavior, which often leads to the death or injury of an innocent bystander.
I saw an article recently that pointed out that the term "gun control" is used by gun fetishists as proof that "liberals" are attempting to cancel their God-given civil right to own a deadly weapon. A more accurate term would be "gun violence regulation" aimed at regulating who, and under what circumstances, a citizen can own and use a gun. Hunting and home defense would be legitimate uses, whereas carrying an AR-15 into Costco (or anywhere in public), or allowing an alcoholic wife-beater to own a gun, would not.
The gunner argument that other forms of dangerous goods are not protected by the Bill of Rights, and are rightfully regulated, is on its face non-sensical -- any dangerous item is a potential threat to life and limb and can be rightfully regulated. All forms of Constitutional protections are subject to regulation in the public interest: speech, assembly, commerce, representation, and the list goes on.
The right-wing and the American Republican Party in particular, support organizations like the NRA, The Proud Boys, QAnon, the KKK, and other racist, homophobic, and bigoted groups because that is the America they want. Guns are just one excuse to further their goals of bullying and intimidation in order to achieve their fascist goals. January 6, 2021 was just a start.
