It is a valid point Zadok makes about it depending on who you are speaking to. If you are talking to a non-Christian then they would equate anyone who takes the bible seriously as a fundamentalist.
I however would associate fundamentalism mainly with the Brethren movement and independant mission halls. They are characterised mainly as dispensational, AV only and the women would be required to wear hats at church services. They would be quite legalistic in terms of alcohol, dancing, cinema, TV etc
I think they are more common in Northern Ireland than in Britian. You may recall Bill Clinton coming to Belfast a number of years ago when the Lord Mayor, also a fundamentalist, delivered a few lines of a mini-sermon in his welcoming speech. He took a lot of flak, even from some Christians, but I thought all credit to him for declaring to the crowds and the worlds media the honour of Christ.
I would not group all Free Presbyterians as fundamentalists but I would include a fair number of them in the fundamentalist camp. ie a sort of 4-pointer fundamentalist; they are not total dispensationalist!
