Regardless of the validity of the signage, keep in mind, if carrying past invalid signs, one should be very familiar with the trespass laws of the jurisdiction. In general, in the USA, the owner of private property, or his designee, can eject just about anyone for any reason. Failure to immediately leave when asked/told do so, can get one into trouble for trespassing. Sue the establishment later, if justified, but get out when asked/told. Protest from outside the property boundary.
The above is not legal advice, but is practical advice.
Each state's laws could be different, so know the laws of your own state. In GA, the "signs" do not mean a thing. If the place is not a place the law says I cannot carry, then I can ignore the signs. If a representative of that place sees my weapon, they can ask me to leave. If I refuse to leave, then the police can arrest me for trespassing, but I will not have violated any gun laws. This is another reason I do not open carry.
