How does the author develop the idea that the kkk has been unsuccessful in its goals?

The author developed this idea by citing how this group used violence and intimidation to ensure that civil rights were not granted to minorities but this was ineffective as the lawmakers passed many civil rights laws in the U.S.

Explanation:

The KKK group which had its beginnings right after the end of the civil war and the beginning of Reconstruction has experienced so many rises and falls. They persecuted blacks and prevented them from voting.

Their third significant rise in the 1960's also did not end successfully as their aim of restricting the passage of Civil Rights laws was ignored by the lawmakers. They have witnessed massive decline in membership and have also been unable to use the internet to tout their hatred.
