text: Knowledge and understanding.  How can you say something is false or claim not not believe if you don't know the contents of said things?  A broad knowledge base, even if some of the topics you don't believe in, is never bad.  If you don't read about it you might not understand something going on.  Let's take Scientology and Tom Cruise for example; if you just listen to what Mr. Cruise spouts it sounds great and viable but it isn't until you actually READ about it that you understand the fallibility of the statements he spouts.  Without that knowledge it is easy to get sucked into things that are wrong and harmful.  The more we learn about what others believe the better our society will be.
