Thinking about the question posed in the OP more deeply, I'm personally well acquainted with only four RF'ers who have substantially changed their religious beliefs down the years while being on the forum.
@Rival herself, obviously, having converted to Noahidism / on a pathway towards Judaism from Christianity (and a few other faiths in-between, her longest being Zoroastrianism but also briefer forays into the likes of paganism, atheism and Luciferianism),
@Treks who has gone from being a neo-pagan, then almost a decade of "on-off" affiliation with Sikhism (in which she struggled to relate to the religion culturally and flirted with Unitarian Universalism) but is now a convinced Protestant Christian,
@metis who was a proselyte reform Jew with Buddhist tendencies when I first met him but has since converted to Catholicism and also
@Conscious thoughts who has gone from Falun Gong (if I recall rightly) to Islam and Sufism.
I'm not sure I know of any others beyond those four, at least with whom I'm very well acquainted.
Such "paradigm shifts" in worldview would seem to be rare things, overall.
