The Term "Fundamentalist" As Applied To The Secular

On a linguistic basis, I would like to ask that I be called an "extremist", "dogmatist", "fanatic", "zealot", or any of a dozen similar words, rather than "fundamentalist". Before atheism, I spent a quarter-century in fundamentalism, and I know its etymology. Given that I reject loyalty to heritage and tradition, it makes no sense to claim that I call for a return to them.
