As far as long guns go, like anything else, it depends on what youre using and what your skills are.
My idea is a short barreled, pistol griped, mag fed gun, not your typical rifle or shotgun. Something select fire and suppressed is even better.
I always have a pistol on, no matter what, but if I thought there was the need to repel boarders, or deal with something where a pistol would be a poor choice, Im certainly going to grab something thats more appropriate. No matter what, I have a lot of options, and options are good.
The "nutjob" comment....., well....., its pretty obvious it was meant to annoy and belittle. Dont let it get to you. A lot of comments like that, are made by those who feel certain weapons shouldnt be allowed in "our" hands, especially if they think how the guns and/or their use might be perceived, will affect them in some way.
Ive always found it amazing how many "gun" people think you shouldnt be able to own or use scary looking, or worse, full auto weapons, especially if they think it somehow might make them look bad, or might interfere with their interests. I know a number who I have no doubt would throw those of us who they dont approve of or agree with, under the bus in a heart beat, especially if by doing so, they think it would put them in a better light.
When a "gun" person calls you a nutjob over your choice of gun, that tells you a lot.
You going to point an AR at her until you find out she lives 3 doors down?
That all depends on what shes doing and how shes acting. Like anything else, certain behavior draws certain responses.
And really, what does it matter what you have with you "to point"?
The other issue is, you make it sound like the only choice someone who has a rifle along, is to "point" it at someone. A rifle is simply another weapon, and responses are the same with it, as they are with a pistol, shotgun, SMG, whatever.
