I think there should be space for all kinds of discussion, even those I don’t agree with, but in this case what worried me the most was the authors claim that once a person enters a community to discuss whatever white nationalist subjects, they are told or manipulated into believing they cannot leave, or they are made to watch propaganda videos in order to stay in the group. That crosses the line from communication of ideas to coercion and cult behavior. I don’t know why people don’t see that they’re being treated in this manipulative way, though. Even at my most lonely, I was highly suspicious and dodgy whenever any similar tactic was used on me; I preferred to be lonely.
