(video) Calvinists would say that if someone becomes an atheist, they were never really a true Christian. As a free will theist, I would say a former Christian who is now an atheist is an apostate. They also may have had a false, counterfeit conversion and thus were not a true Christian. The logical fallacy must be understood and applied reasonably.
Those who think Dawkins is a genius are fools.
If the WT understood theology (the basis for their views is authoritarian structure like Catholic magisterium, not the Bible at the end of the day). They list Luther, Wycliffe (trinitarians) as true heros of the faith, yet consider Russell and Arius in the same category (despite the former being trinitarian and the latter being Arian/anti-trinitarian?!). Theology is coherent, not incoherent.
Theology proper is still biblical truth about God and His world. Comparative religions/apologetics deals with the false views of god (s).
