I was getting mad, then I read your last line!
It’s an interesting thought, why is calling a lie a lie so taboo?
Then there are excuses, one old preacher I knew said, “An excuse is the skin of a reason stuffed with a lie.”
Amen.
Hard to really say, but I would offer this --
Modern society is built upon worldliness, vanity, and pride. We've built our own Tower of Babel in our vast societies of "heaven on earth". We try to make ourselves happy by buying things. We try to make others happy by funding big government programs. It's all empty. Very empty. So many of us are alienated. We have trouble with friendships in the modern world. Many families are deeply fractured -- but still we persist in an unnatural level of self-esteem and pride in all we have, and in all we think we have accomplished.
If anyone starts to say "The emperor has no clothes" or "You're living a lie" ... well, then ... that just might bring the whole world crashing down around our ears. That would be ... uncomfortable. So, please, don't use the "L-word".
