On this site are very capable people and much to learn. Rejects from powerful religions, that contributed to mankinds advance, are good examples for us. what is your inspiring historical APOSTATE figure? My pick:
Johann Keppler,--- who lived in central Europe at the time of the reformation. The Lutheren church disfellowshipped him for his habit of researching and exposing wrong teachings in sermons. nevertheless,
Keppler, a Mathematician was the first to define his three laws of planetary motion, still used today to calculate the orbit velocity, distances of planets from their sun(s). He was right in exposing religious error, facing the consequences and successful in advancing mankinds search for understanding reality.
it does not get much better than that.
