Legit question here... does that include the actual Pagan Pantheons because they would be real world religions otherwise you're showing a bias against Pagans and non-Christians.
I suspect the line is that the "fantasy versions" of the pantheons count as discussing "mythology," whereas most discussions of Abrahamic religions count as "religion" because of their ubiquity in modern culture. The religion is sufficiently intertwined with the "gods" that you can't fully separate the two. But discussing the way they handle angels on Supernatural doesn't cross the line.This is a question that interests me too…
What is the line between discussion of real-world pantheons vs discussion of real-world religion?
I'd guess it would be on qualifying real-world religious practices or comparing them as better or worse than one another, but by saying we can talk Norse Gods and Egyptian Gods and Greek Gods and Celtic Gods (which are printed in the 5e PHB!) but not about Levant Gods suggests that the rule only cares to protect practitioners of the latter and not the former.
Or are we not allowed to talk about the above 4 pantheons printed in the PHB because real world people currently worship them?

And yes, there are Pagans and neo-Pagans, but most people know Thor more as a comic book or legendary figure than as a god they actually worship. So discussing those gods in the context of the mythology that's been written about them is fine.
