Ideas versus Beliefs

The usual argument I hear or talk about is how we kill for beliefs.  We fight for them.  Whereas ideas are far more malleable. You can be wrong with an idea more often and more comfortably than you can with a belief. 

The thing that has me wondering now is why we feel the need to push beliefs on others.  It isn't enough to believe them.  Instead we force others to see as we do and believe as we do.  Is it gratifying?  Does it reassure you that you are right?

In a way it seems the need to convert others to your beliefs is a sign of a weak argument or belief.  Or just perhaps a sign of character.  It shouldn't matter what others believe.  The point remains, it is what you believe.  Inform others if you feel the need, but there is a difference between informing and stuffing your beliefs down someone's throat.

I'm ranting a bit today.  Apologies.
