The risk of having a gun in the home

[DanTex]

53. In other words, 30,000 gun deaths a year is not really a big deal.

Suicide
That is a risk that I choose to accept for myself. I don't need you as a nanny. If I decide to kill myself, then that is my choice.

Good for you, but suicides are still deaths, and there is ample evidence that gun availability is a significant contributor. As a reflexive libertarian, you probably also don't think that you need the government to inspect food, or to ensure that doctors have licenses, etc.

Homicide
The homicide rate has been greatly decreased.

Decreasing doesn't mean "low". It's still far higher than any other first-world country, where gun laws are tighter and far fewer crimes involve guns. And, over the last decade, the entire decrease in gun homicides can be attributed to increased survival rates from gunshot wounds. The rate of gunshots from assaults is increasing.

Justified homicide

A few hundred annually. Versus 10,000 homicides, 20,000 suicides, and 700 accidental deaths. You do the math.
