Yes and no.  If we're going to talk about the 'post-fact' world, one of the biggest misappropriations of truth I can think of is the insistence that everything is equal - all nations, all people, all cultures, all talents, all endeavours, etc.  From grade school on, the implication is that all students in one way or another are doing equally well (this becomes clear when schools started handing out awards for 'participation' - ie, the kid showed up).  

This relativism is patently untrue, since outcomes are obvious.  The only equality that's really meaningful is that everyone should be treated equally before the law (if you're still religious you can also say that everyone is equal before God).  For the rest of it, there ARE better and worse people, cultures, novels, paintings, lifestyles, endeavours, nations, etc.  It is not all the same.  Exceptional (though not infallible) people and their vision molded our current world.  I certainly hope there are more of them out there!
