Alex,

My zero hazard comment was in regard to you seeming to imply that I felt Zubrin was justified in saying zero hazard. I don't, and hoped my reply there would clarify that.

Of course you are correct that there was nothing technically wrong with your in between comment. I was referring to the common perception which would result from using that term. Most would not read that comment and think the odds were orders of magnitude different.

By PC squishy I also meant taking a stance open to a wide range of interpretation in order to avoid offending people. I don't mean to imply that was your intent, but rather your wording was suitable for such a stance.

How about some comments on the examples of possible relevance I raised?

Regards,
Mark
