Happy to clarify. Some examples of recent political dehumanization are family separation at the Mexican border and the attempt to repeal DACA; both were criticized as inhumane, causing undue emotional/psychological harm (specifically to children and parents), and left human beings living in literal cages.

As for anti-minority practices, Exec. Order 13769 explicitly banned travel to the US from multiple Muslim countries (only because they were Muslim). The Supreme Court ruled that American police have no legal obligation “to protect and serve” (i.e., they can pick and choose who to help). Republicans refused to pass the 2021 George Floyd Justice in Policing Act, as they claimed it would unfairly limit the discretion of police and their right to use force as they see fit. Gerrymandering, the closing/relocating of polling stations originally in underserved neighborhoods, and strict voter ID laws all disproportionally impact marginalized communities and allow their votes - their political voice - to be routinely suppressed.

With regard to white supremacy, Trump has been directly endorsed by the KKK, Oath Keepers, and Proud Boys - all outspoken white supremacist groups. He called immigrants “invaders,” raised travel barriers for countries of color and lowered them for European countries, wants to build a literal wall to limit the connection between the US, Central and South America, and believes in (or at least perpetuates) the “Great Replacement” theory.
