But that's what conservative means. It means adhering to traditional values and hierarchies for their own sake.
These professional organizations that refuse to accept criticism, refuse to change practice in light of evidence of in this case poor workmanship, and refused to let the state of the art grow are the very definition of conservative. Especially when they yield their power to crush critics pushing for equity, progress, or rights.
I'm not sure if there is a more conservative stance than the one where you refuse to accept any criticism and then lash out at the critics.
