Seriously, CPL? Where you reading your history?
When Hitler came to power in 1933, Jewish organizations around the world protested, and did indeed announce/organize a trade boycott of Germany. You're damned right they did! But don't think that is what started Hitler's war on the Jews. The reason for the boycotts? Adolf Hitler's clearly articulated beliefs about Jews and race and Germany's future.
Have you read Mein Kampf? That was dictated in 1923, for pete's sake. I suggest you read it. There's far too much within those covers for me to deal with it all here, but everyone should read it at least once in their lives if you wish to understand the evil that men do.
In 1922, Hitler was asked in an interview what he would do if he ever had full freedom of action against the Jews. His response?
"If I am ever really in power, the destruction of the Jews will be my first and most important job. As soon as I have power, I shall have gallows after gallows erected, for example, in Munich on the Marienplatz-as many of them as traffic allows. Then the Jews will be hanged one after another, and they will stay hanging until they stink. They will stay hanging as long as hygienically possible. As soon as they are untied, then the next group will follow and that will continue until the last Jew in Munich is exterminated. Exactly the same procedure will be followed in other cities until Germany is cleansed of the last Jew!" (quoted in John Toland, Adolf Hitler. London: Book Club Associates, 1977, p.116)
By 1930, though Hitler had no legitimate power, his SA brownshirts stormed the Potsdamerplatz and destroyed the Jewish-owned shops there. This was the first "organized" attack on Jewish interests in Germany.
My point? By the time Hitler's power was consolidated/legitimized in 1933, the world knew full well that it did not bode well for the Jews of Germany. Jewish organizations worldwide attempted to organize boycotts to draw attention to the potential dangers before it was too late. Obviously, they failed.
And you are a sick fuck if you can sit there at your keyboard and speak of concentration camp details being exagerrated. If only 1/1,000,000 of what was documented was true, it would be more than any of us should ever have to witness or live with. But that's not the case. See, there are a couple of factors at work here:
1. The German military machine was meticulous in its record-keeping. The perpetrators themselves documented the vast majority of their crimes.
2. Photography and moving pictures had both become portable, convenient, and practical by the time of WWII, so everything was visually documented on an unprecedented scale.
It happened. And no amount of revisionist history from the likes of you will change that fact.
