Apparently Andrew Joseph Stack struck a nerve with a lot of people, despite the spin from several sources attempting to portray him as crazy and to marginalize all who sympathize with him. Within hours following the plane crash and the spread of information about his manifesto, dozens of Facebook support groups for Stack were created. However, these were swiftly closed down by Facebook. I have not yet seen the argument for doing so, although at least two news outlets have followed up on this development:
