What? The author of the video simply didn't make it available for germany. Stop that conspiracy bullshit. 

I can find plenty of evidence, but before digging some up, my question is, what do you consider acceptable evidence?

He's not allowed to make it watchable in germany. Its german law there to not spread Nationalistic socialism propaganda. Or the video will be taken down.

Not even worth it with someone who doesn't even know [or pretends to be surprised] that Holocaust denial is illegal in the country he claims to come from.

Acceptable evidence is when you can't find something that contradicts of that evidence.

The less Nazi propaganda, the better.

So, pictures of dead bodies would suffice? Or would you say that I'm somehow taking it out of context?

You should always look at these things with the most objective mind possible, but attricities commited are undeniable and inexcusable. The holocaust as the prime example among them. My great-grandfather from one side escaped one of the trains bound for a Nazi concentration camp (no Jew though), while my great-grandfather from the other side died during allied bombardment.

I don't think anyone is denying the atrocities of war here. The treaty of Versailles was absolutely rubbish and they had absolutely every right to be pissed off. To deny the holocaust?

I think if people  are so sure it happened. Then you should be able to research, investigate and able to talk about it. Yes there were Nazi concentration camps, but they were labour camps. No gas chambers, with people tucked into small spaces and then injecting zyklon B into a room. Some concentration camps had Theathres, libraries and more. But you have never heard from them right? I would really like to hear your great-grandfathers story. What did he tell you that he saw there?  There are several witnesses and testimonies that have been debunked are false. Which means there are survivors that have lied. And because of what? money?
