Myths are fine, if you like that sort of thing, but religious myths get treated by some as historical events, with both symbolic and actual meaning. That's OK for dead religions, the Norse gods, the Cathars, Druids and what have you. With living religions it matters that people treat these stories as 'gospel'. They should be free to do so, but why should we have to judge and react to their belief systems any differently to how we judge or react to climate change deniers, or the followers of David Icke. Sure, be nice to people, mostly, but feel free to take the piss as well.
