Just to be clear, I don't think the OP was saying that he ever harassed someone for not carrying. I thought he wrote that he stopped himself from [or before] doing that. Maybe he harassed his brother-in-law, which I might consider if I had a sister. In any event, I'm pretty sure this isn't about confronting strangers about their not carrying. That would be psychotic. I understood this was more about our internal thoughts when we see other people in public and our thoughts are turned toward consideration of carrying. Maybe it's a normal, non-paranoid threat-assessment like someone else wrote, or maybe it's just our internal dialogue because we're conscious of carrying and sometimes wonder if other people are or we're made aware that they're probably not. It doesn't mean that our presumptions are right. They don't have to be. Our judgments about people are often biased and incomplete, but we make those assessments nevertheless about their looks, their clothes, their car, their age, their means, their background, whether they're carrying, and probably dozens of other things.
