I checked this out, and it's appalling. I looked at other articles, as well as the one you suggested. Helga, if you want people to support you, please take my advice and direct them to sites that are not revisionist. I know that the site claims that it doesn't deny the Holocaust, and that's somewhat truthful. What is DOES do is blame the Jews for the Holocaust, which is almost as bad. Basically, it's inflammatory and chooses to publish (or link to, because it's trying to avoid prosecution under German law) the most obscure and not necessarily factual articles. There is often a kernel of truth, but it is so hidden in warped opinion that we can't trust it. AS I have said again and again -- Consider your sources and ask if they are credible. This source isn't -- unless we write an article on propaganda and hate groups and how effective they are at convincing people.
One of the things about history is that our picture is always expanding. You are correct that many people are only now learning about the Heimatvertriebene -- just as 30 years ago, people (especially non-scholars) in English-speaking countries were really beginning to learn about Stalin's purges -- mostly through reading "The Gulag Archipelago", which topped the NY Times bestseller list. Documents are hidden. Governments cover things up. Historians constantly rewrite history to include more knowledge -- and sometimes that revises the big picture.
What I'm trying to impress upon you is that most of the postwar picture you want included is real -- that is, ethnic Germans, counted perhaps into the millions, were either exterminated or expelled from their homes in areas that fell under Communist control. But we don't play comparative victims here, and we also have to include facts that unfortunately don't fit your picture. I think I can speak for everybody when I say we want the truth -- but we want it to be told responsibly, and not by revising history in ways that at present seem entirely unwarranted.
