Watch this get spun as justification for the government to have an "off" switch for the whole net or the entertainment industry to be able to kill a site at whim, without due process. (Both laws that congress wanted to pass this year.) Meanwhile the Corporate Supremes rule election-buying by corporations is free speech. For such a simple statement guaranteeing a right to the people, it sure has been mangled.
There weren't any death threats on it, just distasteful messages. No-one was forcing Zeoli to read any of this, and many other public figures have their share of hate sites dedicated to them. This is definitely protected by free speech.
