One of my parishioners is a young historian, Dr Tim Stanley. I enjoy his rather quirkey thought, he amuses me, delights me, sometimes outrages me but always leaves me questioning my assumptions.
I also enjoy reading what he writes, have a look at this, about American creationists.
He also has a blog. His specialises in American history - I think of him as a second Alistair Cook - maybe some American bloggers might link to his site.
