To me, it's fine enough if people want to own guns but it would be much better if advocates did it without peddling factual distortions like this.

Midwest states have lower gun homicide rates than the many European countries despite having the highest gun ownership rates in the US.

The mass shootings that get media attention are a drop in the bucket compared to daily inner city gang violence that jacks up US gun stats. And taking guns from law abiding citizens isn't going to stop gangs from shooting each other.

(0.2 + 0.2 + 0.3 + 0.5 + 0.1 + 0.2 + 0.3 + 0.2 + 0.1 + 0.1 + 0.4 + 0.3 + 0.0 + 0.2 + 0.2 + 0.0 + 0.5 + 0.0 + 0.5 + 0.2 + 0.1 + 0.2 + 0.0) / 23 = 0.208

There is not a single U.S. state midwestern or otherwise that has a lower per capita gun homicide rate than that average. The two lowest are Vermont (0.3) and New Hampshire (0.4), neither of which are in the midwest. The closest midwestern state is North Dakota at (0.6) The data also shows there are plenty of midwestern states with per capita gun homicide rates well above 1. Your claim is incorrect.
