After this the ACLU went after another suburb called "Bethany". Bethany is a little town within Oklahoma City that was founded by the Nazarene church. Built around a Nazarene college. The symbol of the college, among other things was on the city seal. This had to be removed. The city lost in fed court but decided not to appeal to the Supreme Court because of the cost, and because of Edmond having just gotten kicked.
LA county will not win this in court. Until we take back our courts, we cannot live in freedom.
The SCOTUS did not rule on that kjam. If the SCOTUS had heard it I am confident that the SCOTUS would have ruled that because it reflects the history of the community, that it would be constitutionally permissible to recognize that history in the seal.
You may be correct that the LA county may not win this at the 9th circuit since the 9th Circuit worships at the altar of Satan himself. But the SCOTUS has overruled the 9th on almost every major constitutional question that has been brought before them in the last 20 years.
LA county does not want to spend the resources to take this to the Supreme Court. In essence they are cowards.
