A black man was President, he didn’t end systemic racism.
How does anyone end human nature? Racism is based on discrimination and our ability to discriminate--- telling the difference between food and poison, safety and a threat, what we like and dislike, is INGRAINED in us over millions of years. We have food we like, art we like, music we like, cars we like, and people we like. Human nature. You might find one woman sexy and another not. For the most part, we don't have much control over this.
So discrimination, telling things apart, is part of our basic nature, but the word has been made a negative connotation, yet you cannot even drive or walk down the street without discriminating! This time, it may be whether you have a green light or red, traffic coming or not. So racism, the process of liking some people but not others, is but a tiny part of discrimination.
That said, actual /racism/ as truly defined, really begins when you ACT on your personal feelings in a way to literally help or hurt others based solely on race! It may be to give a job or deny a job based solely on a person's race. Then it becomes prejudice with malice. That is racism. But today, the issue of racism has now been morphed into a political football, no one is going to end racism, not Trump, and obviously not Obama, as if anything, despite there being less racism or disparity of opportunity and equality today than perhaps ever before, blacks especially just keep riding the matter of racism as an opportunistic vehicle for attention, politics and advantage.
