Retaining these networks on the air allows us to follow and annotate those sad folks who actually believe and act upon the propaganda and sedition aired on these sites. However, there are easier ways to keep tabs on and trace the insurrectionists and half-wits amongst us.
Now, it is more important to remove the bile spewed on these networks from poisoning our civil discourse. These networks are not a part of our civil dialogue. Rather, they are pure purveyors of hate and insurrection. Removing these networks will allow for a broader national discussion on what constitutes free speech and opinion as opposed to advocacy of violence. Our body of true citizens is competent to make the distinction, but only on a platform of discussion, not talking-points propaganda.
