Let's talk Gaians

[Drake]

The belief that bringing life to a previously lifeless ball of rock is worth killing over would be considered irrational by most everyone. We're not talking about destroying a natural ecosystem, we're talking about creating an ecosystem where there is none, and never will be without outside interference.

That's the irrational part, and I've said it's irrational on a level mostly only seen among certain religious groups. There are lots of other violent terroristic groups, but generally they kill for (to put it bluntly) better reasons, or at least more understandable reasons. If the Gaians were killing for financial reasons, or because people were starving, or because life (in any form) was getting destroyed, or because their land was being taken from them, those would all be somewhat understandable and rational.

That leads to the other point, the reason why I see religiousness among the Gaians. While I say that their level of irrationality equals that of some religious irrationality, that's not the reason why I see them as religious. I see them as religious because their (irrational) reasons for violently opposing dead world terraforming sound religious. 'Even a lifeless planet has value, and should be let to evolve on its own, untouched, however the universe sees fit', etc. That belief is fine, but it sounds like a quasi-religious belief, even if they don't call it that. It's the taking of that belief and killing over it that makes them seem irrational.
