When I was a child I had a revelation; if Santa isn't real then the tooth fairy also isn't real.
Then growing up, if the moon landing isn't real then nothing (of the same kind ) we are told is real.
This is such an oversimplification. Both are, honestly. Because your parents lied to you, you now thing anything they say is a lie? And now you're trying to apply the same logic to global society?
Let's not even get into what you consider to be a lie, that's another entire Pandora's box.
