Ivo Pogonowski books

[Jaga]

Did any of you had a chance to read any of Ivo Pogonowski;s books - related to Polish language or history. I have links to his books:
culture.polishsite.us/links-language.htm

but I noticed that some people are complaining that he is too polo-centric and nationalistic. I had no chance to read any of his books but he seems to have some controvertial views:

I just realized - many of his books are free downloadable! Some are deifinitively not politically correct but some are not devoted to politics. Some are in Polish and some in English. He changed his website, the previous one with a selection of the articles - like his review of the book:
Review of Hitler's Jewish Soldiers, by Bryan Mark Rigg. University Press of Kansas, 2002
must be very controversial!
