The Panopticon/Individuals by religion

Today, I created a whole group of categories under the new category:individuals by religion. A tree containing those categories can be found below.

CzechOut expressed here that this was a complicated matter that should be brought to the community.

His original message was:

I think you need stop and bring it to the forum whether we want to start going down the road of religious classification of individuals. Category:Leaders of the early Christian church is one thing, because that's actually a cat about an organisation. Actually identifying people by their religion is getting into a sensitive territory. Yes, we do have some stories that deal with Catholic/Protestant conflicts, but how finely do we want to take it? Does the fact that there's a wedding in a Christian church in Father's Day mean those people are Christians? I think I'd be more comfortable if we kept the category away from the general area of belief and more towards people who were officially a part of a church (or the heads of church-dominated states). I think Category:Protestants could swiftly become a matter of great speculation, and thereby fall foul of T:CAT NAME. Don't forget, too, that a lot of people fought on the Catholic or Protestant side not because it was their actual religious preference, but because the style of government a particular leader represented was to their liking. And, yanno, whatcha gonna call Henry VIII, since he "converted" (to be super-generous to him) mid-life?

The rest of the conversation can be found here and here. Does anyone have any comments on this matter before I continue working on these categories?
