The WT fears courses such as some colleges require an "ethics" course. The ethics course teaches critical thinking and stages of thinking. It teaches a person to reason and really think for themselves.
A combination of western humanities and world religion taught me in detail how Catholics held full control of christian doctrine until Luther started the protestant revolution. All people who were trying to kick out the human traditions and non biblical doctrines that had been added by Catholics. But then many other splits happened because once the bible was open for interpretation and man didn't need to get 'the truth' from another man, Jesus was the key, then many other branches came from that since many interpret things differently. The bible students did the same thing, they were no different then any other protestant type religion, but then Rutherford took over and added back in many Catholic traits. Put himself as the pope, and organized to all report to him as Catholics all report to the Vatican.
Rutherford turned JW religion from a protestant type and the freedoms it had into a controlled centralized one like Catholic church.
