Last night, I posted about Twitter and Pinterest censoring pro-life opinions. This is about YouTube trying to suppress videos about history.
TimeGhost History produces historical videos on a variety of subjects. The two series I follow are Between Two Wars, a year by year history of the period 1919-1939, and WW2 - Week by Week. The videos below explain what is going on. It's not just TimeGhost, however! This type of censorship has become endemic on YouTube, up to and including removing videos or banning channels because they 'glorify violence' by discussing human history, which as Indy points out (unfortunately) contains a lot of violence.
