When Enthusiasm was a Dirty Word

Apparently, back in the 1600s and 1700s, the English decided that enthusiasm was bad. Too much political or religious enthusiasm was blamed for causing the English Civil War, and so being enthusiastic about such things was looked down upon. "Enthusiasm" became a pejorative term for advocating political or religious causes in public.

I would not be surprised to find that many of the more enthusiastic-personalitied Brits immigrated to the US as a result, leaving their calmer brethren behind, and contributing to the development of our respective national characters.
