Sure. But one of those reasons is "I feel very bad and I have access to a gun".
"The rate of non-firearm suicides is relatively stable across all groups, ranging from a low rate of 6.5 in states with the most firearm laws to a high of 6.9 in states with the lowest number of firearm laws. The absolute difference of 0.4 is statistically significant, but small. Non-firearm suicides remain relatively stable across groups, suggesting that other types of suicides are not more likely in areas where guns are harder to get."
This is perhaps one of the worst ways of looking at it. People kill themselves slowly by many means, including alcoholism, smoking, risky activities (reckless driving, etc.). These are grouped broadly under the term "Deaths of Despair" (see: https://pmc.ncbi.nlm.nih.gov/articles/PMC8221228/). It may be more informative to look at other countries, such as Russia, Norway and Finland, which have incredibly high rates of alocholism leading to a high rate of deaths of despair.
There are many ways to reliably kill yourself. Guns are just the quickest. A serious discussion on the topic cannot avoid this fact.
I cannot give myself chronic fatty liver disease or lung cancer that quickly. I think you know this.
To put it in perspective, California (a state with notoriously strict gun control) has experienced the highest rate of increase of opioid overdose deaths (see https://www.shadac.org/opioid-epidemic-united-states). More generally, deaths to firearm suicide and deaths of despair occur together in rural communities (see https://www.sciencedirect.com/science/article/abs/pii/S00224...).
Are those "suicides" in the classical sense? No. But they are deaths of despair, and from a public health and policy standpoint, must be approached in a manner similar to suicide.
I don't believe you have even attempted (or acknowledged) an opposing point exists on this topic. Your points amount to banal agenda pushing as opposed to seeking to understand the root causes of many challenges today. This is emblematic of (and partially why) there is such division in the USA today: a lack of willingness to study and understand societal problems, particularly those that are multifaceted and require broader reasoning about the topic.
Sure. And my very clear point is that guns help make temporary - even momentary! - despair turn into a permanent end.
I don’t find the pro-gun crowd all that interested in improving social services outside of distracting from the gun issue.
