Agree! The United States always upholds the slogan of human rights, many people say that in the US human rights or human freedom always come first. But according to me, those things are ingrained in their minds and it's like a genetic disease that can't be completely cured and evils like racism that will never go away in their country.
Racism, and discrimination against women, and LGBT will always exist in this world, as long as people are greedy and jealous, these stories of discrimination will never disappear.
Instilling it in their minds is a result of family, community orientation, and education. Racism is controlled by some communities by indiscriminate punishment of the guilty; citizens have an easy time understanding the Government's views on racism and can exploit them. Black race seem to be most recipient of racism, it even comes from the Northern Africans. Education, strong ethics, and hard work should be the cornerstones of black culture to improve their future perceptions.
