I have a lot of experience with anti-semitism - I've followed many extreme forums over the years and it's one of the most consistent patterns - even in oppositional ideologies.

Alex Jones is influential enough that he could, to use the parlance 'name the jew' and most of his followers would follow along with it or he would get new ones. If you think that he would find himself marginalized you are absolutely wrong - that would only occur at one level of society and the polite part isn't close to being meaningful - there is a huge market for this.

Throwing all people you find objectionable into one bucket is an error.
