The most agreed upon counterexample was more restrictive drug laws.
What is the example?
that restrictive laws go against the Enlightenment? or that Prohibition was reversed and people are expecting other drug laws to be reversed?
The idea was that in general, more restrictive drugs laws, which became more common in the 20th century, were a step backwards.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
