Decent people view an apology as a positive gesture and usually reciprocate with the same level of generosity and good faith.This is correct.
Leftists however view any apology as (1) an admission of Guilt and (2) a sign of Weakness that needs to be exploited.
Never apologize to Leftists.
This is one of the big reasons Donald Trump drives the Left into such a frothing rage. He never apologizes, never admits guilt and appears to have no sense of shame whatsoever — and he keeps getting away with it no matter how loudly they scream and stomp their feet. Their entire schtick revolves around shame and guilt: when the Commander in Chief refuses to go along with their show trial, it shows just how impotent they really are.
In Game terminology, what Trump displays is the attitude known as Amused Mastery. It’s the demeanor of a man who brushes away impertinence from his lessers, shit tests from women, and screeching indignation from the media. He answers shaming tactics with shamelessness, phony opprobrium with ridicule, and smarmy moralism with Chad-crafted nicknames.
What he doesn’t do is get defensive, apologize, or supplicate to his would-be inquisitors to gain their favor (or a brief reprieve from their hate). Trump’s attitude is all alpha, with the tiniest of beta morsels occasionally thrown in to utterly disorient his detractors and, more crucially, to peel away more fence-sitters to his side, the kind of disengaged normies who can’t understand why the media is crying hitlerwolf for the millionth time because Ivanka posted a touching photo of herself cuddling with her little boy.
It is true that there are decent people who appreciate and accept an apology without animosity. But they are in the minority.
The really good people do not require apologies. One of the most famous movie quotes ever is Love means never having to say you're sorry.
The bad people, especially the leftists, just use an apology as a weapon, just as police and prosecutors use a confession against a criminal defendant. They do whatever they can to extract the confession, and then use it to put the confessor in prison.
Much of the leftist media coverage of President Trump consists of leftists trying to badger him into an apology that they can use against him. They even want him to apologize for what Roseanne Barr says!
Trump is the President. He should not be apologizing.
