Just because some conduct is lawful doesn’t mean it’s smart, and if one’s self-claimed mission is support of the Second Amendment, exercising that right in such a way that your conduct can be reasonably be expected to scare the heck out of normal people out in public—each of whom has exactly the same vote that you have—is politically idiotic.
My advice is that you exercise your Second Amendment rights responsibly, like adults who both demand that right and accept the responsibilities that come with it, rather than as self-serving adult-children who want rights without responsibility. Because if the second path is chosen, the others in society will strip that right away, without hesitation.
