Like many rational people, I have been confounded by the epidemic of TDS we have seen for the past two years. Having exhausted any other explanations, I have come to the conclusion that TDS is a mental disorder caused by a conflict between the perception of reality and reality itself.
Specifically, those afflicted with TDS believed in the certainty of Hillary's election as President, along with a host of impossible dreams that would make the world a better place. To them, the idea of Donald Trump being elected was not only distasteful, it was an impossibility. Their reaction was actually similar to people witnessing the accidental death of a loved one, which is to wish they could turn back the clock to avoid this horrific event.
Unfortunately, Trump's constant (over)exposure on virtually every form of communication has prevented them from moving on from this traumatic experience. Instead, it is as if they have been forced to relive it every day for the past two years. One could almost feel sorry for them if they hadn't been so vicious in acting out their grief.
Surely that is what you would like to believe. That meshes well in a post-truth political climate.
But consider this; while 2016 presented the two most unlikable nominees by the major political parties, an unlikable winner was elected. The character and comportment of Donald Teump, whether it was as a braggadocios New York real estate developer, failed airline executive, hocker of steaks, suits, vodka and pizza, casino magnate, reality TV game show host, candidate, nominee and president has shown him to be a thoroughly disgusting human being. Hence his sislikable quality.
Next consider this: no one is anticipating another White House run from Sec. Clinton. If the root of your premise were true, the calls would be deafening for Sec. Clinton to enter the 2020 campaign and seek sweet revenge on Trump. Democrats have gotten passed Sec. Clinton, but the Trumpians hang all their suspicions, fears and, perversely, hopes on her.
Next consider Trump policies as they effect citizens who disliked Trump to begin with and/or find themselves shocked, appalled or harmed by those policies. The public outcry over Trump's statements on Charlottesville cause Trump to walk back his statements through proxies like Sarah Sanders and Kellyanne Conway. But Trump himself doubled down muddying the waters and confusing the message.
The Trump policy of 'weaponizing' the plight of asylum seekers, particularly families at our border made Americans lacking the proudly cruel outlook of many of Trump's hard core supporters frankly ashamed that our great nation could act so callously.
When Trump stood on foreign soil and sided with an adversary over our own intelligence community was, in a word, treasonous. His continued minimization of the depths of Russian interference of our electoral process has convinced many responsible Americans that he just doesn't appreciate the problem or, more insidiously, he is more concerned with perceptions of illegitimacy of his election. In other words, he cares more about his image than he does about free and aecure and legitimate elections.
I have always thought that when armchair psychologists come up with the tired old trope that their political opposition suffers from a metal disease is cheap but dangerous. If that lie is repeated often enough, as Goebbels said, it begins to sound true. But there is one psychological term that may very well apply. Projection. The Trumpian may have invested so much hope, belief and trust that infractions that once offended them deeply are now overlooked and accepted as noble, winning qualities. Facing the truth, or at least sincerely understanding the view point of others would leave that hope, belief and trust shattered like a plate glass window after a baseball flies through it. To guard against that epiphany it is common to ascribe the fears of the true believer onto their opposition.
