This is America which really is far gone. But everything American eventually seems to get here too. So the most anti-American segments of our population will eventually pick up this all-too-American meme as well. It is not a good omen. It was this statement, however, that I found the most remarkable (at 4:24):

Those with the highest levels of education have the lowest exposure to people with conflicting points of view, while those who have not graduated from high school can claim the most diverse discussion mates. In other words, the most educated amongst us are also the most likely to live in the tightest echo chambers.

That is quite something to think about if it is actually really true.
