No. Actually. They are not fully enforcable. Depends on local statutes and case law. In many places, they have been found to be exactly as I describe them, violations of the property owners Rights. Namely, the car owners.
You have no "right" to enter another's property in violation of their rules.
Ah, so if they make it a rule to engage in homosexual sodomy you'd be fine with that? Don't be silly. A private entity can no more strip a person of their inalienable Rights than the Government can. It violates the very premise upon which this country was founded.
So, do you have the right to hold a political rally in your employer's parking lot?
If it was a rally inside my car, sure. It'd be an awefully small rally though.
A strange example, but okay, I'll play. Okay, say a private property owner wants to have a gay orgy in his house. A condition of attending the party is that you have to engage in homosexual sex while there. If not, you will get booted out of the party. If you refuse to engage in homosexual sex, can the owner of the property deny you an invitation or kick you out? Of course.
A private entity can no more strip a person of their inalienable Rights than the Government can.
Your rights have not been stripped. You are not forced to work for a particular employer.
If it was a rally inside my car, sure. It'd be an awefully small rally though.
So, as long as you are sitting in your car, you can violate your employer's rules? That is just a ridiculous position.
For some reason I first read that as: It'd be an awefully smelly rally though...
