"You better not do _______, because if you do, they'll write a law banning it!"
You must be some kind of intellectual heavyweight to come up with an argument like that. Because what you are advocating for is, in and of itself, a de facto ban. Except that it's not a ban that exists in the real world, enforced under the threat of violence; it's a ban that exists only in the minds of those who voluntarily agree to it. If I had more "friends" like you, I wouldn't need any enemies. No, I prefer my tyranny to come in the form of men and women wearing suits and robes, who sit up on a dias, and wield pens and gavels. The State, in other words. I know those people are not my friends. I don't need anyone calling themselves my friends telling me to create tyrannies in my own mind. No, thank you, I will go about my business as a free human being without any such chains being placed on me, voluntarily or otherwise.
My reasons for carrying a firearm are entirely rational and any argument against my doing so are doomed to failure. I know this because I am the only person in existence who is responsible for my own safety. I would carry an AR-15 for the same reasons that I would carry a .45, except that carrying a .45 has now been declared a criminal act. The reasons for doing so have not changed, but they do now take on an extra emphasis as a form of political protest. Surely you would not blame a person for exercising their right to freedom of speech?
I will also not accept guilt for the irrational feelings and actions of others. I do not own them, or their feelings, or their bodies or their minds. Blaming me for the irrational feelings of another when they see me carrying a firearm is like blaming a black person for the irrational feelings of a racist. Any irrational action to any action of mine is the responsibility of the actor, not mine. Nobody is to blame for laws against the free exercise of openly carrying guns, except for those who actually wrote the laws. I do not possess the power to enact any law that may be enforced by a body of armed men; that power lies solely in the State and its agents, and I can assure you that I would never pretend to have anything to do with that organization of criminals.
