Fools paradise embodies many things.

People who talk about people, situations or events that do not contribute to their evolution live in fool's paradise. For example, if I input content into a social media system that upsets one of it's users and they react and debate the numbers, they are a citizen of fool's paradise. Not only are they on platform that is not serving them a tangible benefit or profit in the real world, but they are now attacking someone in the real world from the fantasy world.

Let's say someone unfriends you on a social media platform because of something real that you said. This is their way of denying reality in an effort to sustain their fantasy. They are not interested in what's happening in the real world because if they did, then they would have to acknowledge it and that would mean they have to leave fools paradise.
