History

technically they are called chirstian fundementalists. but in america if you say fundemnetalists people will know you are talking about christian fundemnetalists. Maybe in other parts of the world it wouldn't be as heavily implied when you say fundmentalist, as religious fundementalism is not exclusive to christians. Funnily enough, fundmentalist is often used as a standin for biblicial literalist. That is the techincal term for people who are young earth creationists, atleast generally speaking they are almost always biblical literalists. This could be very dependent on culture though. Biblicial literalism isn't a very common term among lay people though.

Practically speaking though it's all semantics.
