Why does the Government hate Anti War Movements?

Why does the American Government hate when we speak out against it? I mean the First Amendment is right there, why does our government feel the need to attempt to police what we say against them? These are all questions brought up when discussing the Progressive Era in class and further developed as we adventured across sites like Antiwar.com and The American Conservative, both sites that I personally have never heard of. We were asked to discuss why that is, why we had not yet heard of these sites or why they aren’t more mainstream then other sites, overall I think it has to do with fear of the government of the American spirit. 

    When doing a simple google search of “Why does the Government hate Anti War Movements?” I kept running into articles discussing the backlash surrounding the Vietnam War, and I feel like that's a good starting place for this discussion. During this time period America had many outspoken citizens who were against the drafting system and felt as if America was going into a war that had nothing to do with the U.S. They participated in protests, some peaceful some not, yet even if they were demonstrating peacefully local police departments would get involved leading to escalations of the situations. 

    Yet even with these ‘giant’ movements we still see a minimization coming from our government, which brings me back to the original question; “why haven’t I heard of websites like Antiwar.com or The American Conservative? 

    In this article by History.com, it mentions Nixon's initial reaction to learning about the Anti-War protests, in it he stated that “that antiwar protesters constituted a small—albeit vocal—minority that should not be allowed to drown out the “silent majority” of Americans,” demonstrating this idea that the government wants to minimize these voices. The government realizes that if not a lot of people realize other people agree with them, maybe they’ll feel like an odd sheep, and just choose to conform to the ideals and ideas the government wants.
