I could understand the argument for factoring people’s feelings into policy in some cases, but let’s take this study as an example.
Handguns are responsible for far more harm than AR-15s, but this study shows people “fear” AR-15s more. A policy that is based on these findings and not empirical data may attempt to reduce gun violence by addressing AR-15 ownership. Thereby not having a major effect on reducing actual gun violence.
A policy focusing on reducing handgun ownership would be much more effective at reducing gun violence, despite people not fearing them as much.
