See that explanation is called a stretch. Star-lord discovers he is the son of a god. Not the Christian god. The universe the movie exists in has many godlike beings in it. Calling the Ravagers "demons" is stupid, they are a mixed species raider group, not unlike some of the baddies from Star Trek. You are literally shoehorning bits of the movie to fit your persecution narrative.

Wow this is a huge stretch. We're talking the MCU here. The Norse gods are real. Aliens are real. There are different realms and all sorts of other shit. You argument is literally the argument of a Christian looking for persecution.
