Beware of Russian involvement.
Lt. General H.R. McMaster wrote a book that was published this year called "Battlegrounds". In it, he explains how Russian agents and a Russian internet agency called Internet Research Agency, a front for the GRU (one of the Kremlin's intelligence arms) uses the internet to sow political and social discord in the United States. In 2016 (the previous election year) it reached 126 million people on Facebook, posted 10.4 million tweets on Twitter, uploaded more than 1,000 videos to YouTube, and connected with more than 20 million users on Instragram. How many Americans do you think they've reached this year?
Their strategy is to identify and create divisive content and market the content by creating "click farms" to manufacture popularity and draw attention to extreme messages. Their aim is to make the user feel like a large number of Americans are against them. They also contribute financially to extremists groups.... I'm not making this stuff up. This is straight out of the book and it was written by a retired US Army general.
Another interesting fact from the book... this agency, the IRA, began creating content in 2015. Of 1,107 videos, an astonishing 1,063 were related to BLM and police brutality.
