No, I agree with the GP. There's a lot of people who buy guns in order to feel powerful and fantasize endlessly about having a justification for using it. Even if they never shoot anyone they tend to approach any and all conflicts in zero-sum terms. Also, they're incredibly tedious to talk to at parties.
>There's no rational reason for you to say that about a person you don't know. That's ignorant and textbook prejudice.
Why would I have to know the person? Just the fact that he likes owning guns is enough. It's a specific mentality that makes you like those kind of things.
