I am sorry of course I am aware of Rav weismandl and the other sides promoted by galen ross and ann porter.I cant get into it over here,but not everything is always so black and white as it may seem. I do commend you that you are knowledgeable of all publicly aware coverage of the kastner topic (rav weismandl, ross porter etc..) but there is more.I will disclose, that a certain Chasidish Rebbe that I know of (now in the Olam Haemes) a few years ago was going to print a book similar to Rav weismandel, after digging deeper he felt that Kastner did not deserve it and shelved the project. As with any controversial topic the truth,for better or worse is not always easy to find.
Have a very Gut Vuch and Simchas.
