This makes no logical sense. C'mon Crowlogic, even you have to admit that an "uncontested example" if far from saying 100% refuted as in the PGF. So your conclusion of "does not exist" falls apart in the context of your quoted statement.
You want Habituator logic? I'll give you Habituator logic. Nearly across the board Habituators are adamantly in the no-kill camp. No killing no matter what. To me it's the chief driver for secrecy- or should be. But their philosophy fails as they won't lift a finger in the way of proof even after knowing that the rest of the Sasquatch population is at risk for losing a member to someone in the field bent on grassing one. To me this is a case of double-think.
I don't think they consider that even more than one could be shot and dragged onto a slab if there's no notification from the shooter in the field that one had been taken. This tells me that MORE THAN ONE could be at risk, or a family. But as long as it's not by the Habituator's hand then it's apparently it's OK. Saving another Sasquatch or it's family certainly does not appear to be enough to motivate a Habituator to step forward with proof.
For all their "good" intentions this point glares as running counter to the purity of their philosophical reasoning. To me it seems rather dichotomous to the dialogue they have been maintaining for years. In other words, A Sasquatch may get shot- but it won't be their Sasquatch; even though proof could mean NONE get shot. But rather one gets sedated, studied, and returned to the field- happens to many other creatures with no harm done. Most of science today isn't as archaic as they used to be.
