Today it occured me that almost all pagan religions were syncretic as fuck. 'The only true religion/god' concept is was totally allient to them, even the sol invinctus cult didn't refuse other gods, it was just kind of mandatory to honor it. 

Not to mention they changed over time and mixed with other beliefs. 

So today, if you are a neo-pagan(not one of the still surviving ones) and your pantheon does not has god of industrial might, patron god of patreon, subscribers and followers then you're not a pagan, you're pretty much larping.
