This has been a good tool to leverage on people dismissing that our governments "are bad, but not THAT crazy."

Leveraging the fact they are practicing a ritualistic event, on a ritualistic schedule, it wouldn't be too far out of the idea that there is overlap to sex rituals and even as far as sacrifice wholesale. Not all, but you cannot deny some, if not many, would. And not everything all at once.

Is adds the possibility to the dismisser's mind, and begins to notice the patterns naturally.

The best thing is that this event is effective on many atheistic and agnostic believers as well. Cause it's not about what YOU believe, it's about what THEY believe. Adds another level of dread to the reality.
