Many evangelicals (once known for a very prudent and biblical approach to doctrine) are fast becoming as doctrinally clueless as the unchurched people they are so keen to please. At least three decades of deliberately downplaying doctrine and discernment in order to attract the unchurched has filled many once-sound churches with people who utterly lack any ability to differentiate the very worst fast doctrines from truth. I constantly encounter evangelical church members who are at a loss to answer the most profound errors they hear from cultists, unorthodox media preachers, or other sources of false doctrine.
In the church today, there is a growing reluctance to take a definitive stand on any issue. Discernment is frankly not very welcome in a culture like ours. In fact, the postmodern perspective is more than merely hostile to discernment; it is practically the polar opposite. Think about it: pronouncing anything "true" and calling its antithesis "error" is a breach of postmodernism's one last impregnable dogma. That is why to a postmodernist nothing is more uncouth than voicing strong opinions on spiritual, moral, or ethical matters. People are expected to hold their most important convictions with as much slack as possible. Certainty about anything is out of the question, and all who refuse to equivocate on any point of principle or doctrine are therefore automatically labeled too narrow. Zeal for the truth has become politically incorrect. There is actually zero tolerance for biblical discernment in a "tolerant" climate like that.
In the secular realm, postmodernism's extreme tolerance has been foisted on an unsuspecting public by the entertainment media for several decades. A plethora of talk shows on daily television have led the way. Phil Donahue established the format. Jerry Springer took it to ridiculous extremes. And Oprah made it seem somewhat respectable and refined. Shows like these remind viewers daily not to be too opinionated--and they do it by parading in front of their audiences the most bizarre and extreme advocates of every radical "alternative lifestyle" imaginable. We are not supposed to be shocked or notice the overtly self-destructive nature of so many aberrant subcultures. The point is to broaden our minds and raise our level of tolerance. And if you do criticize another person's value system, it cannot be on biblical grounds. Anyone who cites religious beliefs as a reason to reject another person's way of life is automatically viewed with the same contempt that used to be reserved for out-and-out religious heretics. The culture around us has declared war on all biblical standards.
Some Christians unwittingly began following suit several years ago. That has opened the door for a whole generation in the church to embrace postmodern relativism openly and deliberately. They don't want the truth presented with stark black-and-white clarity anymore. They prefer having issues of right and wrong, true and false, good and bad deliberately painted in shades of gray. We have reached a point where the typical churchgoer today assumes that is the proper way of understanding truth. Any degree of certainty has begun to sound offensive to people's postmodernized ears.
