What caused the conservative backlash of the 1920s?

 Since a lot of the culture was changing rapidly in the 1920s, there would be backlash by some group of people. For this era, conservatives attempted to stop this more "morally loose" generation from living their lives.

One example is the 18th Amendment, since so many people began drinking, this amendment was pushed so that the production, transport, and sale of alcohol became illegal. Of course, this amendment did not hinder the population from obtaining alcohol, but this goes to show that the conservatives were making an effort in stopping something that they thought was morally wrong.

Another example of conservative backlash is the Scopes Trial. A man attempted to teach evolution in his science class, violating Tennessee's Butler Act, which made teaching human evolution unlawful. This was the beginning of the never ending arguments between modernists and fundamentalists.
