That's just like if the NAME "alchemy" had been kept and continued to be used for what we now call "chemistry". Changing the name helped the bullshit die away. If it were all "alchemy" we'd have some advanced chemists but also some people continuing the bullshit and asserting that alchemy is legitimate. It's quite unfortunate to keep the name "theology" for the practice of the anthropology of religion or the history of religion.
