Well- people don't like being termed ' antisemitic ' because they voice opposition to what is, demonstrably, a vile doctrine of ethnic cleansing and expansionism. When the time comes, however, they'll find their voice, I believe.
You can bone up on Zionism through WIKI- and the article on its current manifestation, Neo-Zionism- sums it up pretty well. You won't find much criticism of America's role in supporting neo-Zionist fascism though as the media is largely owned by................ Jewish billionaires .
The Nazis were, of course, insane- and the German public was easily led due to the intolerable conditions imposed upon them by the victors of WW1. It's easy to see how things got so badly screwed up- with hindsight. Six million of the Holocaust's 18-20 million victims were Jewish and the Zionist leadership of the day was very efficient in manipulating a severely-weakened British post-war government to allow limited numbers of Jewish survivors to occupy Palestine . It wasn't long before Jewish terror groups turned on their ' benefactors ', killing British soldiers and bombing civilians to get their way. They even assassinated the United Nations peace ambassador, Count Bernadotte. In short they swiftly became the fascist assholes that they remain today.
The really sickening thing is that America still supports their crimes. That's the media for you.
