The secular humanists would understand that the belief in the airplane god was a superstition that was harming people and that their belief in the airplane god was wrong and that their wrong belief was keeping them from finding out true things that would make them happier and less afraid of things they did not understand. Many of you probably have parents and friends who are secular humanists. Secular humanists are people who practice secular humanism. But it really isn't. Humanism just means believing in human beings, which we all are, doing human things, which we all do.
Human beings do human things.
Secular means believing in this world, and in the real things that are in our real world, and not believing in some imaginary pretend world that no one can prove is real. So a secular humanist is a person who believes that human beings live in a real world, not a make believe one. Secular humanists believe that people have to take care of themselves and that people have to use their minds to make things better for themselves, because no god is going to help them, and that all the praying in the world won't do any good. Secular humanists believe the real world and the universe the world is in is all there is. But that is quite a bit, really.
