For those who argue that school shootings are a gun problem, it’s worth considering that in the aftermath of World War I, countless individuals had access to guns without experiencing these widespread, senseless acts of violence for no reason. Therefore, it’s clear that your argument has inherent shortcomings. Moreover, I believe altering gun laws could potentially lead to the establishment of a black market, encouraging individuals to seek illegal firearms, and resulting in an increase in overall violence.
Most people don’t argue that the problem is the guns themselves. It’s who can get them/how easy they are to get by people who won’t or can’t use them responsibly. You’re taking the verbiage often used a bit too literally. Either through ignorance or bad faith, I don’t know.
