A recently released document from the FBI indicates anti-fascists are as violent as those who would overthrow the U.S. government
A recently released Federal Bureau of Investigation (FBI) document titled “Domestic Terrorism Symbols Guide”* links common protest symbols to “terrorism” — another marker in a common theme of conflating militant protest for social justice with deadly terrorist violence within the United States. Groups like the American Civil Liberties Union (ACLU) and the Brennan Center have raised warnings about such documents, citing inadequate protections for people’s constitutional rights.
Not at that level. The director of the FBI doesn't change just because the president does. I'm not entirely certain that the president has the final say in the appointment of the director of the FBI, when the position does become vacant.
Well then, according to your own argument, none of the Democratic presidents, nor the Republican presidents, other than Trump, have either been motivated to oust the sitting FBI director, or opposed faschism. Though Trump embraced/embraces faschism.
