I have to disagree honestly. Many of the near-extinct religions such as Hellenism are moreso just aspect of what culture used to be like. They don't really have many followers (most people are in very small pockets anyway).
"Hellenism originated in and is practiced in Greece and in other countries. Leaders of the movement claimed in 2005 that there are as many as 2,000 adherents to the Hellenic tradition in Greece, with an additional 100,000 who have "some sort of interest"."
Mind you, that came from a 2005 synopsis. Hellenism is a very declining practice, so the amount has likely gone down from then. 2,000 people out of the approximate 7.8 Billion is so small that it would be ridiculous to just appeal to such a small minority. If we go by the assumption it's still roughly the same and take the approximation of current people, 1 in 3.9 million people are going to be followers of this religion. I hope you realize you are more likely
to be struck by lightning in a year than to find someone who would fully worship the greek pantheon.
If we're
that scared of offending such a small group (you're more likely to honestly insult an obsessive of a fictional series if I'm going to be honest), then I guess I would have to agree despite what I said. However, I feel that if some of the profiles are flat out bad, they can become candidates of deletion. Nuking every profile though? That's very unnecessary.
