The churches have a constitutional right to rent the facilities from the school board. The ACLU's version of the Constitution would create hostility toward religion and treat religious speech like second class speech. The churches have just as much right to rent the facilities as the secular organizations. Indeed, if the school were to deny the churches the opportunity to rent the facilities while allowing the secular organization to rent the same facilities, the school would in fact violate the Constitution. This case involves the concept of equal access.
Equal access means equal treatment.
