Well, I guess you and Zubrin have a great deal in common ;-) At any rate, I find Zubrin's zero contamination threat "logic" to be as ludicrously simple-minded as DiGregorio's total contamination threat. Neither of these two extremists is convincing, and neither presents anything more concrete than their own specific heuristic plausibility arguments to support their stances. Plain prudence dictates a cautious approach that lies somewhere between the two extremes, but *probably* closer to Zubrin than not.
