That's where you are wrong. At a certain point contemporary community standards will take precedent.
People of a community demand a certain way of life. They think alike. They act alike. Their kids play together, go to school together. This is what makes a community. People work hard to find these zones of comfort and security. They help each other.
IN light of that, these people are entitled by God to life, liberty and the pursuit of happiness. No government can take that away. The Founding Fathers saw to that.
To that end, if a community wishes to include or exclude, as long as their is no harm, they have that right. So if a community objects to the celebration of something as evil as satan, that is their right. If the people who wish Satan to be worshiped feel that strongly , they can seek relief from the courts. Even then let's say a judge who thinks the Establishment clause was written in Sanskrit decides Satan worship to be a religion, rules in favor of allowing a prayer to Satan, that does not mean the community will allow it.
It is our right as citizens to demonstrate civil disobedience when we believe collectively that a law or judges ruling is unjust.
The establishment clause is a federal mandate and has supremacy over "community standards".
That is true but not accurate.
Example...In a small town near here the government opened every town meeting with a short payer. This has been done for many many years in this town and was more traditional than secular.
A few years ago, a woman who claimed to be a worshiper of a Wiccan sect attended a council meeting and when exposed to the prayer decided to hire an attorney. She filed suit claiming the town violated ( here we go again) the "separation of Church and State".
The town had a great defense but decided to not fight it due to budgetary issues. The attorney representing the plaintiff handled the case
pro bono.
Fast forward to today...The town of Great Falls, SC still opens their meeting with a prayer but keeps the prayer non denominational.
At the end of the day, we get to run our lives the way we want so as long as we bring no harm to others.
There are those who like to say things such as "federal mandate and has supremacy over "community standards", to make themselves feel better.
That's ok. The procedure by which one must lodge a complaint leaves so much lag time, the process of government intervention is really quite useless.
Once again, we're talking about liberty life and the pursuit of happiness vs a person who sees things differently in the realm of religion who has a bone to pick.
People in general are sick of complaining whining "special needs" people who at the slightest inconvenience run to the courts which then rule in favor of the lowest common denominator.
The needs of the many outweigh the needs of the few. Or the one. The masses need not suffer but for the actions or desires of a few.
