This is where things get tricky as the world becomes more politically and ideologically polarized (thanks to the internet), world governments and companies are faced with difficult decisions regarding censorship. During the latter half of 2016 Twitter suspended 377,000 accounts for promoting terrorism, in early 2017 Facebook like YouTube decided to employ a combination of artificial intelligence and human content flaggers in an attempt to find and remove extremist content. For a YouTube this reform was in response to the so-called ad-pocalypse with advertisers leaving the site in droves because their ads would sometimes appear on hateful or extremist videos this, of course, led to an overcorrection on the part of YouTube as thousands of fairly tame videos were demonetized, even some second thought videos were demonetized including any videos that mentioned nuclear weapons or North Korea.

The US isn't alone in censoring questionable content, in France and Germany most Nazi-related and Holocaust denial websites are blocked, communist symbols and imagery are censored in Poland, Lithuania, Ukraine, Latvia, Moldova, and Hungary. South Korea did the same blocking pro-north Korean sites. While some Middle Eastern countries blocked sites related to the Muslim Brotherhood.

The common thread between these instances of censorship is public approval because most of the people don't protest for such content being blocked or filtered because it is alarming or offensive to most of society.
