Did you read? "of all kinds"
here is more clarification:
The Pew Forum on Religion. Read the transcripts for Rick Warren's interview. Rick Warren - May 23, 2005:
On the Fundamentals of the Faith
I read the Pew article and the quote is as follows:
"Now the word "fundamentalist" actually comes from a document in the 1920s called the Five Fundamentals of the Faith. And it is a very legalistic, narrow view of Christianity, and when I say there are very few fundamentalists, I mean in the sense that they are all actually called fundamentalist churches,"
I'm familiar with "Fundamentals" and, in fact, was brought up in a Fundamentalist church. The "Fundamentals" actually covered more than the Five mentioned and were printed in a many volume book and distrubuted to churches. He is right it was a very narrow, legalistic response to the turmoil in the churches caused by liberalism, and rightly so. However the "Fundamentalism" of today is really a charicature of the movement in the '20s and that is what I think Warren is referring to.
Wikipedia: "Fundamentalist Christianity, or Christian fundamentalism is a movement which arose mainly within American Protestantism in the late 19th and early 20th centuries by conservative evangelical Christians, who, in a reaction to modernism, actively affirmed a "fundamental" set of Christian beliefs: the inerrancy of the Bible, the virgin birth of Christ, the doctrine of substitutionary atonement, the bodily resurrection of Jesus, and the authenticity of his miracles. This core set of beliefs was the "line in the sand" drawn by conservative Christians as they battled against the rise of rationalism, higher biblical criticism, and liberalism within Protestant denominations.
The nature of the Christian fundamentalist movement, while originally a united effort within conservative evangelicalism, evolved during the early-to-mid 1900s to become more separatist in nature and more characteristically dispensational in its theology."
Some of his statements (if they are true) are really beyond the pale for a "non-denominational" Christian minister. For instance: "But, powerful as churches can be in working for the powerless, they can't succeed without governments and nongovernmental organizations." As if God's will is dependent upon Government intervention.
Often people who become popular or famous surround themselves with yes men who nod with approval at every idiotic thing the famous person says or does. I suspect that Warren may have fallen into that trap.
At any rate I'm not going to defend him on this.
