what a bunch of fools, right?

First, pick your favorite demeaning word: "Fools," "Idiots," "Morons," "Control freak," and so forth.

Second, apply it to someone who frustrates you: A political party, a church or church leader, a business who let you down, etc

This is how we normally vent our frustration out against people and organizations; however, might there be something to consider about it?

Read these words via an interview with Francis Chan, and apply them:
Jesus threatens hell to those who curse their brother (Matt. 5:22). He's not warning drinkers, smokers or murderers. Jesus preaches hellfire against those who have the audacity to attack a fellow human being with harsh words. 
It's ironic—frightening, actually—that some people have written books, preached sermons or written blog posts about hell and missed this point completely. In fact, some people have slammed their Christian brothers and sisters in the process, simply because they have a different view of hell, missing the purpose of Matthew 5: "Whoever calls his brother a fool may find himself guilty of hell." 
Have you called your brother a fool lately? On a blog? On Facebook? Have you tweeted anything of the sort? So often, these hell passages become fodder for debate, and people miss the point of the warning. Jesus didn't speak of hell so we could study, debate and write books about it. He gave us these passages so we would live holy lives. 
Stop slandering one another, and live in peace and brotherly unity. Jesus evidently hates it when we tear into our brothers or sisters with demeaning words, words that fail to honor the people around us as the beautiful image-bearing creatures that they are.
