Maybe time to post this again. I wrote this long ago and my speech in Turin in 2009 was a shortened version. I could sure add to this today and might have to update it, but the basics remain the same.
If you want to compare Lieder's research to that of Ms. Zumaya, it is imperative you read this presentation. You can then make up your own mind.
Since I wrote this in 2003, more evidence has come to light and I will update this at some point; i.e. the letter from Valentino to Hebertot about Daven, Valentino contracting syphilis as a teenager from female prostitutes, etc. and of course the "letters to Bruno".
Very excited to learn about the new evidence!
