Delusional to think that Trump will be the end of democracy,

  The neurotic defense mechanisms and delusions surrounding the belief held by some liberals/leftists that Trump will be the end of democracy,

baseless accusations, fear-mongering, and hypocrisy:

The left has long relied on controlling the narrative through their allies in the mainstream media and academia. They thought they could smear and discredit anyone who dared to challenge their agenda. But President Trump, a political outsider, broke their stranglehold on power. He exposed their hypocrisy and their failed policies. The left simply cannot accept that their grip on power is slipping, and so they lash out with baseless accusations and fear-mongering.

delusion and ad hominem fallacy:

 That Trump is the end of democracy is a convenient way for liberals to avoid confronting the real issues. They refuse to acknowledge the very real concerns of everyday Americans who feel left behind by globalism and political correctness. Instead, they paint anyone who disagrees with them as a bigot or a threat to democracy. It's a tactic to silence dissent and maintain their power.

overgeneralization fallacy:

As for the delusion itself, the belief that Trump will single-handedly bring about the demise of democracy can be seen as an example of an overgeneralization fallacy. This fallacy involves drawing sweeping conclusions based on limited evidence or specific instances. While concerns about the impact of any leader on democratic institutions are valid, attributing the entire downfall of democracy to one individual oversimplifies the complex dynamics that shape political systems.

confirmation bias:

Furthermore, this delusion may also be fueled by confirmation bias, which is the tendency to seek out and interpret information in a manner that confirms one's preexisting beliefs. Individuals who strongly believe in the narrative that Trump is the ultimate threat to democracy may actively seek out information that supports this view, reinforcing their delusion and disregarding alternative perspectives.

Intolerance, cancel culture, assaults on freedom:

 Their intolerance, their cancel culture, and their attacks on our fundamental freedoms are a clear and present danger to democracy. They want to dictate what we can say, what we can think, and how we should live our lives.

intellectualization and rationalization of emotionalism

One possible defense mechanism that may be observed is intellectualization. This defense mechanism involves detaching oneself emotionally from a situation and relying heavily on rationalization and intellectual analysis. Those who hold the belief that Trump poses a grave threat to democracy may engage in intellectualization to cope with their fears and anxieties by attempting to provide logical justifications for their emotionalism.

selective perception:

Another defense mechanism that could be present is selective perception. This occurs when individuals selectively focus on information that confirms their existing beliefs while disregarding or minimizing contradictory evidence. In the case of the belief that Trump will be the end of democracy, some individuals may selectively perceive and interpret events or actions in a way that reinforces their preconceived notions, thereby reinforcing their delusion.
