During President Wilson's second term, what bills did he and the government pass that would indicate that he/they were trying to legislate morality?

The only bill that I can think of that was passed during
Woodrow Wilson's second term and that would have showed that his government was trying
to legislate morality was the 18th Amendment.  This was ratified in 1919.  The Volstead
Act, passed to enforce Prohibition, could also be categorized in this same
way.

This amendment, of course, is the one that brought
about Prohibition.  Prohibition was perhaps the most prominent example in all of
American history of an attempt to legislate morality.  The idea behind Prohibition was,
in large part, that drinking alcohol was bad for people and that they should be
protected from their destructive desire to drink.  By basing such a sweeping law on this
sort of idea, Wilson and Congress were clearly trying to legislate
morality.
