One of my favorite subjects within the general fields of this forum is the philosophy of Martin Heidegger. Especially with regard to his support of National Socialism.

As far as deconstructionist theory goes, I enjoyed this book immensely:

Historical Destiny and National Socialism in Heidegger's "Being and Time"

I think Fritsche is flat-out wrong in a number of ways, but it's a great read and very well researched, imo.
