I just read that, well I guess we should start a "Is Rick Ross legitfully helpful or a close minded misguided morass"? But we'd have to address each organization they address--and certainly some of the ones they attack are good.
I've heard though that some people have read through the RR cryonics pages and had a better view of cryonics as the allegations were out there, and the cryonicists that respond seemed reasonable--so I've never viewed it as that harmful. Most people don't believe everything they read on the net, and research things further on their own.
