In the modern sense of the term, that is true. However, one could certainly make an argument that Oliver Cromwell, et al were fundamentalists, as well as the original settlers of Plymouth. You could go back even further in time and apply the term to various Catholic orders at certain points in history.

All that being said, I was just using his term (in quotes) for the sake of continuity of conversation, and it was not my intent to lend credence to his application of the label "fundamentalist" to 18th- and 19th-century missionaries.
