The "pseudoscience" was primarily directed at the drift off topic into the expanding Earth and dinosaurs. While specific portions of some arguments on Mars contamination may have the characteristics of pseudoscience, there is nothing wrong with concern over and study of the subject.

I'm not studied up enough on various aspects of Mars science to weigh in with scientific papers and such, but I can see right up front that many advocates on this board seem to have a special feather up their ass on specific areas of Mars exploration and other space subjects*. I'm not naming names, but they're pretty obvious.

This strikes me as grossly premature, considering how much evidence we DON'T have. As an example, by the time a Mars Sample Return mission is flown, it is likely we will have a lot more data from probes that will be landing there beforehand, and more informed decisions may be possible.

The fuss over water vs. CO2 is similarly silly. Within a decade we will almost certainly know for sure one way or the other. Relax. Build the probes.
