[somenameforme]

When it becomes impossible to be able to reasonably comfortably speak against a consensus, that consensus loses any sort of meaning because it becomes impossible to determine whether it's being upheld by coercion or not. It also becomes completely impossible to carry out science in such an environment because such pressures invariably leak into e.g. universities, career opportunities, grants, and so on.

So without being able to reasonably comfortably speak against a scientific consensus you end up with neither science nor a consensus.
