Yes good point, but in the video he points out that:

Hitler tried to get Germans in WW2 to think that Jews were dirty mice. Right? It's in the movie!

Okay, so why be concerned about the "Tom and Jerry" cartoon?
Why the concern?

He must be concerned about the cartoon, because it is clouding the ORIGINAL image that Hitler wanted to show?

Namely that Jews = Mice.

Right? Why be concerned?

Oh the pain...
Because that evil disney guy made the mouse to be good, and old Hitler was right? lol, HAHA! , God what a sicko...
