About half a year ago Donald Trump, during a rally, mentioned that the US would need a different type of negotiators to deal with foreign negotiators (such as the Chinese). He said he already knew who those negotiators were and admitted that these people were horrible people. He created fear by saying that there was a threat, being that weak and incompetent US leaders make bad deals with smart and tough foreign leaders thereby undermining the power and economy of the US. This is a telling example of legitimizing something bad (putting horrible people in power) in order to defend against threats.
As, perhaps, could have been be expected it did not end there. Now, the create fear to gain control cycle is more clearly recognizable in Trump's rhetoric. In interviews with CNN Trump created fear by painting a vivid picture of how ISIS kills people and then laugh at the weakness of the US. Then he argued that we have to become much tougher and that we have to expand the laws to get at an "at least somewhat equal footing." In the CNN interviews he does not explicitly say what kind of measures he thinks but he previously argued (on Fox news) for waterboarding and killing family members of terrorists. Trump's logic: our enemies are bad, we have to become bad, too. Another example of Trump legitimizing violence is what has he has said during his rally's. As this video shows there is an escalation in Trump's rhetoric. This silencing of American protestors, by the way, is an example of how fear is not only created for external threats but also for internal threats.
It is not surprising that Trump is being compared to and called a fascist. Now, I am not necessarily saying that people using these methods, like Trump, have deliberate bad intentions. While that is certainly one credible explanation, an alternative explanation which may also be valid is that they themselves are prisoners of their own fear. Anyone can fall prey to the idea that "we" are threatened by bad people and therefore have to become bad ourselves. But I think this idea is primitive and will never work in the long term. Instead it will set in motion a process of increasing tensions. Don't buy it. Choose rationality.
