For that reason in some cases cult leader's pictures were burned or there were highly confrontational interactions between deprogrammers and their targeted individual. The idea was to trigger an emotional response from the shock, the fear, and the confrontation. In modern days, it is said that the focus should be placed on the following process.
First, it’s essential to engage, rather than ignore, the Trump supporter, which I wholeheartedly believe. Then by asking questions and presenting contradictions around the former president’s behavior, it should be easier to discredit him. For instance, for example, by asking "How does he lie every time he says something?”
The breaking point is supposed to be reached when the subject begins to accept the deprogrammer's position and begins doubting the ideology. Often, it leads the subject to start voicing criticisms and complaints against the new Republican Party. The subject begins to identify with the deprogrammers, thinking as an opponent of the cult rather than as a member.
This approach might appear too simplistic to many, including myself. Some assert that it might cause the subject more harm than good. For that approach to work, the subjects must be convinced that they joined the Trump political movement against their will. They then must renounce responsibility and accept that in some mysterious way, their minds were controlled.
Instead, I believe that many love Trump because he was able to validate their darkest sides and this goes against a breach of their free-will.
