Y'know, If I am at a restaurant, and you walk in carrying an AK variant or any other rifle into the restaurant, I am not going to assume you mean no harm.
It is one thing if you are carrying a pistol on your hip, in plain view. It is another if you are carrying a rifle in your arms...in a restaurant.
Not sure that my reaction would be appropriate. I carry too, if not as openly. I'd have to assume that you meant me harm. And yes, I'd be disturbed just like those anti gunners were, if for different reasons.
For your own safety:
Don't be a dick.
Thanks, assholes, you really helped there.
