As Haidt says, it's harmful to the extent that it contradicts the core telos of academic research, but I don't think it's so harmful that research becomes impossible. Quite a lot of foundational scientific work comes from medieval Christian and Muslim sources whose religious authorities executed people for heresy.
In terms of some outcomes, yes, the research can continue unhindered if they say "Hallowed are the Ori".
Personally I feel like it makes for a very poor work environment, so I sympathize with many who are put in that position. I would prefer it if they did not feel constrained by this type of environment, so that their best work would emerge.
