Your comment proves the point. Thinking that an African American in a hoody should be feared and a caucasian is racist are both assumptions which can be very pernicious.
Who do you mean by "they". Caucasian people? If the election was true that would mean most Americans voted against Trump and most Americans are caucasian. You are assuming that all caucasian people think and act the same which is not true.
Racism is bad and you cannot control what is in someone's heart. Actions speak louder than words. If good things are being done for minorities then good. If they are treated unfairly based on race then that should be punishable.
It says Trump critiqued and criticised Obama. If he doesn’t like Obama does it makes him a racist? He fired a contestant on the apprentice who had not contributed to the job who was African American and they suggest that was also racist.
Didn't Trump open one of the first clubs in Palm beach to Jews and African-Americans. Didn't he date Kara Young for two years who was of African-American descent. Didn't he publicly condemn the KKK, neo-Nazis and white supremacists.
