Although the hateful speech on infowars (especially the comments section) is deplorable, I don't think that is the truly worrying aspect of the conversation going on over there. It is the threatening tone of the broadcasts, articles and comments (and the many actual threats in the comments) that concerns me. He not only fills the mind of his subjects with hate, but encourages them to 'fight back' against the 'new world order', ostensibly to 'protect their rights'(or something like that, you've heard the rants).
For example, when a police officer alledgedly violated someones rights in an article posted a few days ago, Alex ranted about 'standing up against these fascist pigs who are trying to take away your rights'. In the comments section, one man asked 'what would that cop look like with a .50 cal in his head', which was followed by many posters cheering on the statement, including one who 'dreams of it every night'. This kind of baiting goes on everyday there, Alex tells people to feel threatened by all kinds of boogiemen, and the people respond by baring their teeth and riling each other up.
All this crazy gathered in one place lets these people affirm their theories, and have them reinforced by others, leading to them believing there is some kind of consensus that their beliefs are correct. Those who do try to interject some sanity are quickly insulted, mocked and accused of having nefarious reasons for being there. Many believe anyone that disagrees with their narrative in the comments section is a disinformation agent sent to hinder the revealing of the 'truth'.
Also the name, Infowars. If there is a war going on for their minds, as they say, are those who disagree with them their enemy in a war?
