His main point is that human life is equal no matter what race or religion you are.
The one point he didn't touch on was the fact that many Germans (who were probably just trying to survive in the midst of a horrendous war) also lost their lives.
I think the point of the video is that you shouldn't single out one group of victims, but instead realise that WW2 (and indeed all wars) was a tragic, disgusting affair that caused huge losses for all sides involved.
It shouldn't be glorified, it shouldn't be used as any one group's foundation for revenge or compensation, it should (ideally) be used as a point of history that illustrated that wars are the most terrible thing that we can inflict on ourselves as a single species, and that however "correct" or "moral" the justification seems at the time, the reality is one of massive negative consequence for all involved, as well as generations to come.
This isn't saying that nothing should have been done to combat Hitler's campaign, but that the reality of war means that almost everyone involved becomes a victim, and that all victims should be remembered equally.
