In Christianity, "Fundamentalist" refers specifically to a Protestant/Evangelical movement that was named for a series of essays published before and during WWI, which outline certain specific doctrinal positions. The movement arose largely in response to opposing beliefs which themselves date to the mid-late 1800s. Being "unwilling to budge" might make someone a literalist or a dogmatist, but being a Fundamentalist is more specific.

Among Americans who call themselves Christian, few are anything close to true Fundamentalists [0]. Most are hybrids whose beliefs have been assembled in bits and pieces from pastors, books, etc. which includes some fundamentalist-inspired ideas, some ideas that resemble fundamentalist ideas but are actually much older, and some ideas that are completely opposite of fundamentalist ideas. People whose beliefs are mostly Fundamentalist are a very small subset of Christianity, both globally and in the US.

[0] note that "no true Scotsman" is only a fallacy if one is using inappropriate criteria to determine group inclusion/exclusion. It's not a fallacy to point out that James Doohan wasn't really Scottish.

If you want to define "Fundamentalist" to be something other than current real-world usage, that is fine. I'll just pick a new, less 'technical', word: Nuts.

If you are a creationist, you are an utter nut, full stop. A significant portion of Americans are religious nuts.

And, to clarify earlier discussion on the behalf of JabavuAdams, "Online, when someone writes "Christian", it's hard to tell whether they're referring to fundamentalists^Wreligious nuts, or not."

All better?

I define Christian Fundamentalist according to its actual usage within the relevant community [0]. If we were referencing Jewish, Muslim, or Hindu Fundamentalism the definition could be substantially different.

I have already proposed better terms: "literalist" and "dogmatist". Those terms may be insufficiently pejorative for your purposes, but here on Hacker News we have guidelines and cultural expectations against name-calling and incivility.

[0] note that I am not a member of the Fundamentalist, literalist, dogmatist, or creationist communities.

Let me guess, next you'll demand that we not refer to chiropractors or psychics as "quacks"...

If you're interested in serious discussion, whether about religion, spiritualism, medicine (real or "alternative"), or any other topic, you should choose your terminology carefully and remain open to correction when others point out that you aren't using it right.
