Do a person seriously think that Donald Trump embodies the corrupted practice of Pax Americana oligarchy? Donald Trump is exceptional among the US presidents for alienating the Pax Americana media oligarch, exposing their hostility to other countries, staging aggression towards a rich country of British diaspora, stopping funding to their foreign puppets, and exposing the protectionism that Western European diaspora practiced in their hypocrisy. What bad things did Donald Trump actual commited that is not unusual in Pax Americana?
Do you mean the tendency to think that anything that black people holds are gun? This cultural and psychological problem is from the indoctrination by American media to subconsciously associate black people with violence and deliquency which cause errors in quick judgement by police. The American police should realize this racial biases and should be training the police to remove this subconscious racial biases by now. Whether they provide the anti-racist association training or not is another question.
