The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
Indeed, Race relations were strained in the mid-1960s to such a large degree that even those who fought side by side for the passage of the Civil Rights Act of 1964 and the Voting Rights Act of 1965 abandoned each other.
I consider that the primary source of animosity in race relations as the civil rights movement evolved in the 1960s was the fact that white people were afraid that all the legislation changes and demands from African Americans were getting too far and whites felt threatened. At that time of the civil rights movement, black people wanted equality and the same rights as white people, and that idea did not appeal to everyone in conservationist white groups of the United States.
The Civil Rights Act of 1968 was passed so soon after the Civil Rights Act of 1964 and the Voting Rights Act of 1965 because the previous legislation did not address housing discrimination.
Better known as the Fair Housing Act of 1968, The Civil Rights Act of 1968 prohibited any kind of discrimination when buying or renting a house.
These kinds of actions were not applauded by many whites.
