A cool thing about 19th-century newspapers is how forthright they are about drawing the line between acceptable expressions of religiosity and crazy, toxic ones. The key phrases were "religious delusion," "religious enthusiasm," and "religious excitement." Those last two sound like they might be good things but they weren't. It's a paradox of secularism that we're much more reticent about classifying expressions of faith as benign or nuts. Even "fanatic" is by and large a word for the editorialists, not reporters.
