[Antoninus]

how does Xianity get off calling the others ‘mythology’, when the same stories are held by Xians, as ‘truth’?

Possibly because Christianity doesn't have stories of the gods being paederasts, or marrying their sisters, or eating their offspring, or of revealing the future based on the shape and color of animal entrails.

[Terry L Smith]

Instead of ‘possibly’, i suggest ‘plausibly’, (as he buys the man his next cup of coffee).
