None of any of these shootings in MA were explained in terms of who was perpetrating the shootings. But, the guy who defended himself explained the individual who went after him and his. This is part of the greatest issue with blaming inanimate objects. It deflects blame from who actually committed a crime.
I was an anti, from an anti family myself. But, I've never trusted the government, I've always taken an individual/family support approach as opposed to the whole "We're all in this together" approach, and I've always wanted to avoid dependency on others. These tendencies led to my enjoyment of firearms, especially once it became clear to me, that more than any criminal, the government (whichever one) is the most dangerous to people, and historically, the only way to stop government has been force(once it won't accept democratic reforms). I don't think that would have worked on her, because she didn't have the same root beliefs. She clearly trusts the government, and believes the "I am my brother's keeper" etc. concepts.
Exposing her to America's gun culture was probably the best thing. Many times total imersion is best.... She wasn't a bad person. Clearly nice. It was very nice what she did for the guy's son. But, most people who are anti-gun aren't bad, they're just ignorant.
