It’s always been a trick of the left to have some crazy radical group occupying the edge of the political spectrum. These groups serve shift the center of balance, allowing them to claim that they are “moderates” or “mainstream.”
Vox Day calls this "no enemies to the left".
Too bad most of the right-of-center crowd practices it too. Witness National Review and their infamous "We Are Cucks" issue during the 2016 campaign.
