How does the United States brazenly pull down the same "cotton curtain" in the southern United States while denouncing the "iron curtain"? Even after 1954, the high court abolished the apartheid policy, the protection of human rights advocated by the world is still both a law and a practice in most parts of the United States. Before King and his movement, there were many incidents of black people being discriminated against. Rosa parks, a tired and decent seamstress, was once sentenced to prison for refusing to give up her seat to a white man on an Alabama bus. Ruby Boric, a 6-year-old black girl, was bullied and abused by a child in New Orleans because she wanted to go to the same school as white children. Emmett Deere, a black boy of 14 years old, was hunted down by a gang in Mississippi just for criticizing a white woman. Even blacks with higher education still have no right to vote, and they cannot serve in the courts; They can't have lunch with white people at the lunch table; Can't register in the hotel, can't use a room for white people to rest; They can't buy or rent a house of their choice. In some rural towns in the southern United States, if whites cross the road, blacks will even be forced to leave the sidewalk.
