I thought your earlier posts indicated you thought BD was clearly in the psuedoscientist camp.

As far as the Mars factions goes the issue is exactly what are reasonable precautions. Do you do everything possible within reasonable cost constraints then abort the mission at the hint of any problem or do you spend tens of billions for marginal improvements in safety. Or do you take Zubrin's extreme view that you go with reasonable precautions and don't abort the mission under any circumstances because the risks are admittedly low by everyone (even those that disagreed with Zubrin in the PR) but BD's nutcase camp.
