alt Hacker NewsPeople disagree because they hold a different opinion. In many eras publicly expressing differing opinions, let alone publicly challenging established ones, becomes difficult for various reasons - cultural, political, social, even economic. And I think this is, in general, the natural state of society. When people think something is right, changing their mind is often not realistically possible. And this includes even the greatest of scientists.
For instance none other than Einstein rejected a probabilistic interpretation of quantum physics, the Copenhagen Interpretation, all the way to his death. Many of his most famous quotes like 'God does not play dice with the universe.' or 'Spooky action at a distance.' were essentially sardonic mocking of such an interpretation, the exact one that we hold as the standard today. It was none other than Max Planck that remarked, 'Science advances one funeral at a time' [1], precisely because of this issue.
And so freedom to express, debate, and have 'wrong ideas' in the public mindshare is quite critical, because it may very well be that those wrong ideas are simply the standard of truth tomorrow. But most societies naturally turn against this, because they believe they already know the truth, and fear the possibility of society being misled away from that truth. And so it's quite natural to try to clamp down, implicitly or explicitly, on public dissenting views, especially if they start to gain traction.

Plenty of physicists then and now still work hard on trying to figure out how to remove uncertainty in quantum mechanics. It's important to remember that randomness is a measurement of uncertainty.
We can't move forward if the current paradigm isn't challenged. But the way it is challenged is important. Einstein wasn't going around telling everyone they were wrong, but he was trying to get help in the ways he was trying to solve it. You still have to explain the rest of physics to propose something new.
Challenging ideas is fine, it's even necessary, but at the end of the day you have to pony up.
The public isn't forming opinions about things like Einstein. They just parrot authority. Most HN users don't even understand Schrödinger's cat and think there's a multiverse.

I’ve heard this sentiment expressed by several of my friends in academia
It extends to policy as well. I mean look at the average age and tenure of the US Senate.
Or stagnation and disruption of markets.
I want to call this the inertia of incumbency.
