As a German I can just agree what you said about "The Jews" because Nazi Germany was a group too.
Yes. Germany has a got bad reputation in the past and will probably forever be associated with it, but as you said, you can't blame a group because not everyone in the group agrees with the statements of everyone else in the group. I think videos like this shouldn't just exist about "The Jews" but about stereotypical groups in general.
You made it a great start but I think that there should be more videos like this.
Cheers.
