For those same reasons, the health and safety of the public, the State can tell you that you must allow employees to have their personal firearms locked in their vehicles, on your property, whether or not you like it.
When it comes to business, property rights take a back seat to the powers of the government to regulate commerce, since before the beginning of this Republic.
Again I think you are wrong. The Govt can restrict my property use as a business just like they can restrict your property use as a individual.
Your argument is a red herring. You are attempting to paint a picture where business property rights are in a different than other property rights issues when in reality they are not. Your argument is weak as a result.
First of all your arguments from analogy do not hold up. You stated: "You, as an owner-employer have no say in how the State regulates your business. The State can ban smoking, for reasons of the general welfare, in your place of business, whether or not you like it."
These bans are enforced under licensing codes. They have nothing to do with property rights directly. If you want a Liquor Lic or a food and beverage lic you cannot allow smoking. If you are running a business open to the public under a retain business lic you need to keep it smoke free. See its not tell you want you can do with your property it has to do with the lic which allows you to conduct business of a particular form in a particular locality.
For some reason that I cannot comprehend you are trying to argue that the businesses property rights are from individuals property rights. This is not the case. The state has imposes reasonable restrictions all the time on property rights both personal and business. The building code is a perfect example of the Govt's control over use of property. A locality can tell you what you can and cannot build on your property. It can even tell you how you have to build it. etc......
It seems to me that you clearly think your rights are more important than others rights and that you can trample other peoples rights when you see fit. It is perfect example of the blinders that the pro-gun world wears everyday.
If we want respect for our rights we have to be willing to accept that others do not agree and that they have every right to hold their beliefs and impose them within their sphere of influence. To ignore that does our community a disservice IMHO.
I think that employees who have demonstrated competence with a gun should be able to carry at work but it is up to the employer not the employee to make that determination. The property owner is king of the castle and I personally would not want it any other way.
