So is culture. Are you ready to demand culture-neutrality?

It is possible for a culture to at least not be inimical to truth. But to the extent that a religion is not inimical to truth, it has ceased to be a religion.

Would that apply also to scientists who were prevented from getting grants and being published?

If the main reason why scientists don't express a belief is that if they do they would be arbitrarily denied grants and publication, then it would apply. However, in the modern Western world, almost every example* where someone made this claim has turned out to be a crank whose lack of publication was for very good reasons. As such, my default assumption will be that this has not occurred unless I have a specific reason to believe that it has.
