I can't imagine that they are actually "threatened" by fundamentalists (at least in the U.S. or England), beyond the occasional public school district being hijacked by crazies. I can't name a prominent conservative Christian or Muslim anything (outside the area of religion). I can name plenty of U.S. politicians who pander to conservative Christians.

I am actually surprised that a sizable minority of top scientists actually claim a religious affiliation. I would have expected the percentage to be close to zero, but I remember reading someplace that a nontrivial percentage of scientific nobel laureates do identify themselves as "religious" in some way. I don't know if it's just a "social" religious affiliation or if these folks are capable of separating their scientific work from their belief system. I suspect it is the former.
