One hallmark of religions is that they have an institution of higher learning, where the most ambitious and schooled young people go to complete their religious training and enter the world as leaders of their faith. In Christianity, we call these seminaries. I attended Sacred Heart Seminary near Green Bay WI. in the 70's. A seminary is the place where a devout believer goes before he enters ministry. Once this training is completed, he is called to go out into the world to minister to his flock and to convert the unconverted to his form of religion and indoctrination.
The Progressive Left has a seminary, too — a finishing school where the ambitious and well schooled are polished to become "ministers" of their religion. It is the called American university system.
