That still has no relevance to my comment. The poster I replied to said Moore's monument had been singled out. I agree, in a different way. Moore singled it out when he had it made and placed it in the court house, thus creating this mess. The SCOTUS never singled out the display of the TC in their building. Moore did by placing it their and refusing to allow anything else. He started it. The law ended it.
If his free speech rights trump the establishment clause, then the establishment clause is meaningless.
The fact is, he can do anything he wants when he isn't on duty and wearing the mantle of office - once he is on duty, however, his speech rights are subordinate to the establishment clause.
