YouTube just banned Jared Taylor of American Renaissance and Stephen Molyneux (along with less nuanced channels of Richard Spencer and David Duke) for violating their rules on "hate" which includes "alleging that a group is superior in order to justify discrimination".
These channels promote "Race Realism" - the position that the difference in social and economic success between ancestral population groups (aka "races" ) is due to a substantial degree to immutable genetic differences and its effect on culture. They also maintain that while direct racism still occurs, it is a small component to why there are differences in outcomes.
Note: I assume most here agree that YouTube banning these channels is very bad on a 1st Amendment/Free Speech basis. Feel free to debate or discuss ramifications below.
