I was thinking about this the other day. One thing I wondered—are there any examples of “regressions” that occurred in human history because the change in culture leaned too progressive? And by progressive/conservative, I mean in the sense of the directionality of culture, not necessarily their modern political connotations.

For example, Prohibition was a “conservative” movement because alcohol was originally permitted and then became disallowed. Later, it was restored. What is an example of something that was previously disallowed, became allowed and widely acceptable for a period of time, and then became disallowed again such that it is still disallowed or considered immoral today?
