There were no gas chambers, hence they were not "death camps."

Your ex FIL was subject to propaganda, just like the rest of us.

If there were no gas chambers on the German side -- which the allies acknowledged shortly after liberation -- then the FACT is that he could not have seen "death camps." He saw prison camps/labor camps for sure. We had them, too.

Many photos and film footage were faked.

Emaciation was real, due to the lack of food supplies, due to the Allies bombing train tracks and roads that were used to deliver food and other supplies. The German people were also in bad health.

You see such photos presented to you, and you ASSUME they were from jews held in prison camps.

But you don't KNOW that. Many of the famous photos have very different captions in different books, indicating that whoever published the photos didn't really know what the source of the photos were, or who they were of.

The Germans were bombed into oblivion, and their dead bodies were piled high. There are photos of bodies being pushed around by a bulldozer, BUT that dozer was American. Such photos were taken AFTER the war, and Americans/Brits were pushing the bodies around (to pile them up and bury them, I presume). Plus, some American/Brit was taking the photos that were published. Were these of jews in the camps, OR Germans who were killed in either the British bombings or the American-controlled death camps of Germans after the war was over?

We don't know.

Images like this showing piles of dead, emaciated bodies have been shown to unsuspecting audiences, inducing psychological trauma and fear in their minds, in order to sell the idea that the Germans systematically murdered millions of people (especially Jews) in “death camps”. The fact of the matter is that when the war was ending, the German-administered labor and industrial camps were not supplied and many people did in fact perish in horrible conditions. But that does not prove that the Germans were systematically murdering people in these camps. It simply demonstrates how deceitful, brazen and ruthless the Western and Soviet propagandists were in their efforts to demonize and slander the Germans.

Also, some of the iconic imagery associated with the Jewish “Holocaust” turns out to be photographs of dead German civilians murdered in Allied fire-bombing campaigns, which were presented to the masses as “proof” of German atrocities. Again, the shameless, deceitful behavior of the Western Allies and their Soviet Communist partners knows no bounds.

The iconic “Holocaust” imagery shown repeatedly to mass audiences is never put into context. The images are simply shown, and we are expected to believe that the “Holocaust” was a real event.

I can't find them offhand, but there are numerous examples of photos that were faked or altered, or of non-jews that were claimed to be of jews in the camps.
