A lie can cover shame, sure. It’s done all the time. We can tell lies we can argue aren’t actually lies, they are just ways of sparing some pain, to ourselves or others. There are gradations in lying, too. We can lie in a way that is, arguably, basically truthful. We can leave out just one key detail, more or less accidentally, and satisfy ourselves that this small omission was completely justified. Without that troubling detail, the rest of the story makes more or less complete sense, so what is the harm of the “lie”?
Because we now live in a culture where a lie, unless told under oath and punishment for perjury is actually pursued, is no longer a big deal. So, I lied, so what? I wasn’t under oath, only loser chumps take an oath not to lie. Everybody lies, and you’re lying if you don’t think you’re a fucking liar too. And if you don’t lie, you take the fucking Fifth, like a man.
The analysis is fine, as far as it goes, which is not far at all. When you accept a lie you choose your poison.
Why is the United States poised for an era of stochastic terrorism, angry, unbalanced men, rabid lone wolves, poised to do deadly violence to themselves and others, always ready to be triggered by an angry suggestion that this person or that is deserving of death? 
Because the widely accepted lie that one party is run by demented, murderous, child-raping Communist blood-drinkers is as accepted (among a solid 30% of Americans) as the one that Blacks are irrationally angry about nothing, that Jews are about to replace all “white” “legacy” Americans with brown dupes, that elections lost by your candidate are rigged by these all-powerful Commie traitors, etc. If you are angry, and alone, and everyone else in your social media silo also faithfully believes these demonstrable lies are true, and you have lost faith in everything else, and an assault weapon is legal and readily available in your state, why on earth wouldn’t you take out some of these demonic scum in your heroic last act on earth?
What is the cost of accepting a lie, being faithful to defending a lie to the death? It costs you your integrity, your authenticity, your credibility. It also costs the ability to ever solve a problem or conflict based on what actually caused the problem or conflict.
As in politics, so in our personal lives. If saying something that is true enrages or humiliates someone you know, you tactfully avoid the topic. Some topics are easier to avoid than others. If it is a shameful single event, unrelated to anything else, that you both acknowledge is mutually painful and worth avoiding, it’s reasonable to agree to not bring it up anymore. If the topic is honesty itself, that’s a tough bridge to cross with your relationship intact.
“Uh, OK, we can’t talk about why it’s better to be honest than dishonest, OK, let me try to remember never to say anything that might bring up that flaming bag of shit. Honesty is overrated, LOL!”
To me, the cost of my integrity, authenticity and credibility is too high a price to pay, in most situations. Then again, I have a lifelong issue in that regard. Life itself, making a living, often requires limiting the scope of one’s integrity, authenticity and even credibility, in the name of going along to get along. Too much insistence on a right to be whole, and treated by others with the same care you give to them, can make you as welcome as an agitated scorpion at a baby shower.
On the other hand, if you are honest, you will understand that the price of lying is almost always unacceptable.
If we don’t trust each other, what kind of love do we have between us? What kind of savage world do we live in?
 Walking neo-Nazi pustule Steve Bannon called for the death of Anthony Fauci, and his family, on his podcast the other day. Free Speech, bitches. First Amendment, you fucking blood-drinking Fauciist cucks!
