You can drone on and on and on - it won't change the fact that other religions (and non-religious groups) are being discriminated against. Public property should not be used for promotion by any of them. They are quite capable of blinding us with their ON-PROPERTY displays.
Many groups of people of certain religious followings own no property. Why should they be limited in the free exercise of the practice of their religion simply because they do not own land of their own?
