Both the linked article and the source it cites focus only on the male results from the threatened gender identity experiments. I'd like to see the female results too. With only 5 female mass shooters in the past 50 years I'd like to see if that were only being blamed on an over-representation of males or if sociology points to a corresponding under-representation of females. Also, the maps presented make me interested to see regional comparisons. On first glance, the places that are largely rural, but also have looser gun laws, seem to have fewer mass shootings. On one hand, of course, less people means less to shoot and to do the shooting. But any town over 5 people could have a mass shooting. Why are they such an urban phenomenon? Could the access to unregistered and untraced weapons contribute? The article seemed to focus on just a single primary cause, but it'd be interesting to see additional factors too.
