If you believe in conspiracies, even if they are true, like the one that the FBI conspired against the Trump presidency, then you are a domestic terrorist:

“The FBI has released a 15-page document warning of the dangers of “anti-government, identity-based, and fringe conspiracy theories.” The law enforcement agency says that these are “very likely to motivate some domestic extremists to commit criminal, sometimes violent activity.” The document seems to recommend increased social media and web censorship. The FBI assesses anti-government, identity-based, and fringe political conspiracy theories very likely motivate some domestic extremists, wholly or in part, to commit criminal and sometimes violent activity. The FBI further assesses in some cases these conspiracy theories very likely encourage the targeting of specific people, places, and organizations, thereby increasing the likelihood of violence against these targets. These assessments are made with high confidence, based on information from other law enforcement agencies, open-source information, court documents, human sources with varying degrees of access and corroboration, and FBI investigations. One key assumption driving these assessments is that certain conspiracy theory narratives tacitly support or legitimize violent action. The FBI also assumes some, but not all individuals or domestic extremists who hold such beliefs will act on them. The FBI assesses these conspiracy theories very likely will emerge, spread, and evolve in the modem information marketplace, occasionally driving both groups and individual extremists to carry out criminal or violent acts. Indicators that may lead to revised judgements or cause a change in the confidence level associated with this assessment include a lack of conspiracy theory-driven criminal or violent activity in the near to long term or significant efforts by major social media companies and websites to remove, regulate, or counter potentially harmful conspiratorial content. So what do they consider conspiracy theories? A few of the theories and topics mentioned in the document are QAnon, Pizzagate, the New World Order, various child-sex trafficking ring theories, and racial extremists. Interestingly, there is no specific mention in this document of Antifa and their theories, despite the fact that they’re decidedly anti-government and confirmably violent.”

     The FBI has the following definition of a conspiracy:

“…A conspiracy theory is an attempt to explain events or circumstances as the result of a group of actors working in secret to benefit themselves at the expense of others. Conspiracy theories typically allege wrongdoing by powerful others (for example, public officials, business executives, scientists) or societally marginalized groups (for example, Muslims, Jews), and are most prevalent among individuals with extreme political views. Some conspiracy theories point to weak circumstantial evidence, but ignore stronger evidence that would refute their claims. Consequently, they are usually at odds with official or prevailing explanations of events) While a conspiracy theory refers to an allegation that may or may not be true, a conspiracy is a true causal chain of events. Real conspiracies involving illegal, antidemocratic, or harmful activities by high¬ level government officials and political elites have been exposed in the past and it has been argued that such plots have encouraged conspiracism in society. Relying on the premises that nothing happens by accident, nothing is as it seems, and everything is connected, conspiracy theorists tend to view every bad outcome as the result of an intentional decision by an evil actor, dismiss disconfirming evidence as “fabricated” by the conspirators, and connect a wide range of seemingly unrelated occurrences to suggest a larger plot. Despite sharing key characteristics and at times featuring similar themes and intersecting plots, conspiracy theories vary greatly in their scope. Some are narrowly focused on a particular event or set of events whereas others suggest broad, expansive narratives that link multiple conspiracies in complex ways to portray a group of evil actors working to manipulate society on a global scale.”

     Basically, the FBI is saying that if you believe that powerful people act behind the scenes of daily life to rule the world, then you are a terrorist, in a nutshell. It is a crazy position, worst than any tin foil hat conspiracy theorist. What is advocated is what Eric Butler called the “idiot theory” of history, that things just happen, for no reason at all. That acausal view is not scientific at all.
