I know the video was edited, it's by PragerU. That's not the point though, it was just a story to point out that not all things about other cultures are offensive.
And it's funny you ask about Kimmel, because I actually know the person who did those bits (she was the offscreen voice for the first few years and is actually the interviewer in this video). She said that while it was edited, they didn't have to edit it much, because about 80% of the people really were that dumb.
There is a bias in that we see such videos, find them shareable, notice their existence but really there's absolutely no reason to use either the Kimmel or PragerU vid as anything other than light entertainment.
That doesn't mean the underlying argument they propose can't be defended, just that the videos have no explanatory power whatsoever.
