I think the fact that you find other people's beliefs frustrating says more about yourself and how you deal with the world than about the value of those beliefs.
Emotional intelligence is real, and being easily frustrated (specially when that frustration comes from being so sure that you're right and someone else is wrong) is a sign of low emotional intelligence.
