Religious groups, not government, should erect and sponsor religious displays. Religious symbols such as crosses, menorahs and crèches belong on private property, not the shared space of government. In some cases, government land may be used by private groups as a type of free-speech zone, and religious groups might choose to erect religious symbols at their own expense. If this happens, all groups (religious and non-religious) should have access to the space with none receiving special treatment. All messages should be heard in this space, even those that are deemed controversial.
