Mars Society has a dream, and an honorable one: the manned exploration of Mars.
Calling it a fantasy, in the context of your presentation as factually conclusive the evidence from the Viking Missions, is a misuse of the language.
I predicted a year ago that people like you would succeed in making Mars off limits to manned landings.
I thought I was going to be proven wrong.
Now you are here using the time-worn playbook of the anti-nuke and other psuedo-science fear groups of forcing people to prove the unprovable, while maintaing control of the standards.
If you do this right, you could get the Sierra Club or Greenpeace mailing list, and for a small fee use it to make yourself rich. Hurry! the market is low and if you buy now, you can get really rich.
