Architecture should not be "we have always done it like this". If you don't write down why though it will become that. Often there are good reasons that things have always been done like that - those reasons may or may not still be valid but if you don't know what they are it is hard to evaluation. More than once I've seen someone rethink a "we have always done it like that" and discover the hard way why they always did it that way.
I've never seen a company with a good way to write down why they do things though. When someone even tries nobody reads those documents.
Or it might be an architectural decision to change the hierarchy of some organisational structure. Again, it could be the correct call for the time, but as things evolve over a year, it may not be sufficiant a year later.
A year isn't a bad time to review, and if the decision is just a "yeah, duh, of course we'll continue", then it's a really quick conversation, but at least you're thinking about things.
I also understand things are different in many places, but I think the argument is too heated right now, maybe everyone needs to take a step back and think in a more "international" way?
Someone in the linked thread suggested a new tag altogether for religious content, that might be a sound decision.
Given the level of NSFW material in some of them (sex, violence, etc), I think it's not surprising they're getting labelled as such, even without the link to a religion.
