I read what he wrote a few times and seriously doubt this guy thought it through that far. You, on the other hand, appear to be quite articulate and able to put your thoughts into well thought out ideas. He struggled with correctly organizing sentences.
It’s far more likely he just wanted to make himself feel bigger than he is, much like the folks who drive ridiculously large trucks, live in the city, and work in an office park.
IMHO, he was being arrogant and using his constitutional rights to flaunt it. He was just being a provocative ass by exercising that right in that place.
I find this opinion quite interesting. I see that your State is listed as Rhode Island, so that explains some of your mindset, as Rhode Island is one of those east coast states that have exhibited a rather strong tendency to severely restrict the right of people to keep and bear arms. Many people in other states find it incredible, for example, that you have to apply to the state for a permit to buy a handgun! Rhode Island is also one of the few states left where you can be denied a permit to carry a concealed weapon at the whim of the person issuing the permit, though this is being challenged in the courts.
While it is legal for a permit holder to carry openly in Rhode Island, apparently very few if any do. I suspect that the informal word has been put out: Open carry and we will revoke your permit.
Can you tell me if my suspicion is correct?
The larger point being they are his Constitutional rights, and he may flaunt them for all lawful (if impolite) purposes without let or hindrance.
I for one will not so much as criticize his actions because, as I said, "those who practice it where it is legal cause it to be normatized in their surroundings whether or not that is their primary motivation."
I love to see OC-ers in action, for just that reason. I'd be one myself, but I decline to subject myself to the infringing laws that prevent my ability to buy my sidearm of choice the way I can buy a socket wrench.
