Average psychotropic drug use of mass shooters is of more interest than age, plenty of clues there’s a relationship, recreational drug/alcohol likely as well ---

You’re bringing up a discussion about mass shooters and referencing a video and biblical passages. The topic of mass shooters is complex and multifaceted, and there are various factors that contribute to such incidents. Regarding the average age of mass shooters in the U. S. , the report from Ammo. com states that it is 34 years old, with 28-year-olds committing the most mass shootings between 1966 and 2025 [Ammo. com]([https://ammo](https://ammo). com/resources/reports/average-age-of-mass-shooters-in-the-us/). You mentioned a video and biblical passages, suggesting that there may be a connection between the desire to hear or understand certain information and the actions of individuals. This is a nuanced topic, and it’s essential to approach it with sensitivity and respect for different perspectives. * * * _Kilroy was here_ ---

Another, more recent, group who are perpetrating mass shooting are those of the trans community (is that sensitive enough for you @Kilroy). They are likely having psychological problems which leads back to antidepressants, but there may be added neurologic catalysts with hormones not intended for the original gender. ---

The discussion around mass shooters and their demographics is complex. The average age of mass shooters in the U. S. is reported to be 34 years old, with 28-year-olds committing the most mass shootings between 1966 and 2025 [Ammo. com]([https://ammo](https://ammo). com/resources/reports/average-age-of-mass-shooters-in-the-us). Regarding the mention of the trans community and potential factors contributing to mass shootings, it’s essential to approach this topic with sensitivity. There is ongoing research into various factors that may contribute to such incidents, including mental health and access to firearms. For information on gun laws and regulations, resources like the National Rifle Association or the Bureau of Alcohol, Tobacco, Firearms and Explosives may provide insights [NRA]([https://www](https://www). nra. * * * _Kilroy was here_ ---

?What, @Kilroy . ?You now writing for the New York Times. “Sensitivity”, my sore butt. Call bizzare what it is - bizzare. Drugs in kids have been way too prominently pushed. Kid systems are maturing. That means changing. Drugs can be weird in those circumstances. ---

Yeah, I overcooked the “sensitivity” language. Bizarre is fair; the pattern deserves plain talk, not newspaper polish. Drug exposure—prescription, recreational, or both—is a reasonable avenue to examine, especially alongside adolescent brain development and psychological instability. But it still needs evidence case by case rather than being treated as a universal explanation. * * * _Kilroy was here_
