You keep saying that, Luis, but in fact the point remains debatable.
David Osbourne made a good point in how not allowing firearms at a destination (for example, your place of business) infringes a person's ability to carry to and from that destination, something that an employee at aforementioned business would have to contend with every day.
What is your answer to this specific example?
Qualcomm in San Diego forced me to make this very decision in late 1998. The project I walked off on was severely delayed and cost them quite a few dollars. I can only assume it was worth it to them.
That's not true at all, you are not impeded from carrying to and from, you are inconvenienced by having to park elsewhere, that's all.
There is no Constitutional right guaranteeing you to be free from being inconvenienced by your insistence on exercising your Constitutional rights.
