No that's not the question of this issue, that is a generalization since you fail to identify the branch of government or the specific facilities.
Judge Moore had every right to decorate the court house in the manner he explained to his constituents during his election campaighn. Because the people of Alabama chose him as Chief Justice this issue is about the people of Alabama.
The question is.. Just because you can justify your own submission, should the rest of us bend over along with you? The answer is NO
If there's a question of submission to judicial tyranny, then let me reframe it for you. Should the citizens of Alabama submit to Judge Moore redefining where his authority comes from, what religion is proper and right, and what religious messages need to be given on the rotunda of the supreme court?
You're right, the answer should be no.
Because if it isn't, you may see Satanist "decorations" on the rotunda. Or atheist "decorations". Or atheist sermons from the bench.
Moore could use private funds to put up a billboard. Perfectly proper. He could use private funds to take out newspaper, radio and television ads. Perfectly proper. He could write a book (on his own time) and get it published. Again, perfectly proper. He could preach in churches or on street corners, on his own time and not wearing his robes, and it would be perfectly proper.
He's using his government office to promote a particular religious viewpoint. That is not proper.
