Copernicus was an expert. Those who have spent years laboring to understand a subject do occasionally ignore the bright upstart who has mastered the field and then proves them wrong. But that doesn’t oblige them to credit ignorance as serious argument in the name of “being willing to listen to unpopular opinion”.

And this isn’t about credentialism either. You can tell the lion by his claw; a knowledgeable non-credentialed expert will not be dismissed as easily.
