Many here have complained that Derrida is hard to read, or worse, simply makes no sense. You may take a side in this, if you like. But I would encourage you to read some short piece of his instead. In so doing, and as the interview itself remarks on reading, you may make your own interpretation.
@mbrock has listed several items. To these, I add what my instructor for composition at Deep Springs (himself a student of Derrida) assigned us, "Declarations of Independence." It is but a nine page talk on the US Declaration of Independence. But within it, many of Derrida's persistent concerns on language and action come to light.
You can find it online, starting at page 5 in this PDF: http://blog.lib.umn.edu/cole0384/academics/files/Derrida.PDF
