First, I have always been of the school of thought that if I don't like a particular movie, TV show, or public figure, I simply don't watch or listen to anything associated with them. In short, I change the TV channel, click to another video, stay away from a movie, or ignore the public figure whenever he/she comes on whatever screen I happen to be watching.
I'm definitely not one of those narrow-minded egotistical individuals who fatuously thinks: Well, because I don't want to watch Alex Jones, NO ONE should watch Alex Jones! Put the content out there on whatever available platform and as long as it abides by whatever rules/regulations that govern that particular platform, let it roll. (Of course, I'm not saying it's permissible to stream live sexual assaults or the advocating of physical harming someone.)
While I felt for those featured in this documentary, I don't think the director gave full scope to some of the incendiary stuff those individuals were spewing which resulted in them being labeled "hate mongers," "white supremists," "right wing reactionaries."
I agree with another review that asserted that the documentary turned Jones, Loomer, Watson, and the others into "victims." It should be considered that they all had a role in their own victimization. It's not like they didn't give their respective platforms reasons to ban them.
Still, I'd recommend watching the documentary if for no other reason to be made aware that social media can and will censor contact, regardless of Constitutionally guaranteed rights/privileges.
