One of this guy’s myriad followers shot up a pizzeria and threatened several lives. Others have spent years attacking and harassing the Sandy Hook parents and ruining their lives. Still think it’s all fun and games, and about simple disagreement of dissenting opinions? It would do everyone a world of good if people would stop pretending like every conflict in this world is as basic as a discussion of opposing viewpoints over coffee.
He's a total jerk and it's really hard to feel sorry for him. I don't like using an individual or group's audience to judge their legitimacy though. One major religion had followers who flew planes into buildings. Another had followers who bombed abortion clinics. One major political party had a constituent shoot up a baseball game. Another major political party had a constituent run down demonstrators with his car. I don't think we should start asking for Democrats, Republicans, Christianity, and Islam to be banned from the internet (even though it could improve the place). Alex Jones has done enough personally for you to impugn him without having to resort to what people who listened to the show did.
I'm nearly an absolutist when it comes to free speech and I realize I'm in the minority in that opinion. Lots of people support free speech as long as it doesn't offend their own sensibilities and in doing so believe they are strong supporters of the concept as well but it's the speech that is objectionable, that's repugnant to the majority, that most needs protection. Further, when the platform for speech reaches such a scale that non-governmental entities removing speakers they disagree with will stifle that speech then I think it needs protection from those private parties. An oligopoly of internet giants all removing speech they mutually dislike can relegate it to being unheard and speech that is not heard... well trees falling in forests comes to mind.
