The one quote provided is nothing near incitement violence, in the legal sense. I'm now in the icky position of defending Daily Sturmer because I believe in the First Amendment and this latest campaign against one web site feels so contrived and politically correct. Yes yes, I know that the First Amendment doesn't apply to Namecheap or godaddy or cloudflare. But this has gotten downright silly.
As another commenter noted, these large companies have no compunction hosting/registering domains for sites that actually do incite violence and actively ruin people's lives... like jihadist groups or ripoff report, a site that makes it an active business model to defame people online, destroy lives and careers, and then extort people to remove that content.
This whole daily sturmer campaign has gotten to the point of being nothing more than a way for companies to pretend like they care or want to prevent a type of speech they don't like, but in reality is picking on one site that is mild in comparison to the other things these companies tacitly approve of.
