An addition to the Global and Local Character list, extra column--religion--would make it much, much easier to discriminate against other players based on their religion.
And therefore grant mainstream religions an addition advantage over less mainstream ones, as it'll be easier for them to stamp out smaller faiths. The idea has been brought up before, and countered with this same argument. For example, how long do you think the Blood Cult would have survived if people could easily track its growth in membership? And the Blood Cult probably brought more to BT than Eretzism, the Order of the Druids, Daishi, Omioism, and the Order of the Dragons combined. Just to name a few off the top of my head.
