:/ your making the mistake on saying religious scholars are all scholars.
Really all they do is find "new" stuff to try and get people to either convert or defend their religion.
Fun as that may be, they really don't contribute to the world outside of that.
They are scholars, but I never singled them out as being absolutely needed. And ofc the human population needs them, like 90% of the world is religious or something (they believe in some sort of supernatural power etc.) /
