BGutzMan; that is a great, and objective point. I truly wish the world worked like that.
It's not just gun rights that are stepped on in the private world, free speech also does not exist (I know, only govs are covered by the Constitution), and we see examples of such controls "everyday."
I believe it's not just a gun issue, or just a speech issue with these employers and other private entities, it's a power thing. The guy in charge has to order everybody around, right?
Question (non-sarcastic, I truly don't know), what gun advocating business owners do you know allow their employees to carry at work if they legally can? Gun shops not included. I personally know of none.
