This is the sentence. To support the government school principal for any reason is to support government school spiritual tyranny.
The principal may have discerned that it is inappropriate to “wear” a rosary—the school probably has a stringent dress code (hopefully).
As to your post back to me, the words are wildly fanatical; as if you are not able to rationally hear and respond to another opinion. I’ve stated to you that I, too, am disgusted with public schools yet you rave at me for reasons known only to yourself. Like Sarah Palin. Only SHE knows.
