Grim linked to a story about grandparents arriving to take custody of their grandson, but being prevented from doing so until they had given up some gun rights - and the judge was quite explicit about this.
I work among these human service people who disparage gun ownership and gun owners. They put forth bad reasoning about European gun ownership and homicide, or curious statistics about gun death that are circular, but my conclusion after years of knowing them is that this is not what really worries them. If they come from big cities, they are sometimes really worried about black people with guns but won't say that (though they come remarkably close unintentionally when speaking privately). But in NH, they are usually worried about white people from another culture.
It's pretty basic. People who own guns are not from our culture. They come from over the mountain. The people over the mountain are dangerous. They want to enslave us and take our food. They are stupid and cannot be reasoned with. Beware.
They have absolutely no insight into how often their public comments reveal what they are thinking. I used to think like that myself, and I hear them saying now what I said then. They believe that only dangerous people want to own guns (though they admit that most gun owners aren't very dangerous), and they believe that having a gun nearby activates violence and makes everyone more dangerous, and the two effects are additive.
