A demand is an affirmative statement verbally or in writing. I issue no such statements. To carry against someone's wish is not a demand for them to change that wish.
Even if you choose to see it as a demand, it's no more of a demand than someone taking their business elsewhere, or joining a boycott.

You insist on having your gun on your person, even if the private property owner wishes otherwise. You are thereby demanding that they allow you to carry, even if you don't directly express your desire to them or announce your actions to them.
You're violating their rights, even if they don't know it, just as you are breaking the law by doing 100MPH on the highway even if you don't get caught.
A lot of justification for your actions.
