Freedom of speech and the ability to have different opinions is infinitely more important than people's feelings.
Most of the "free love" generation came along thinking their parents were squares and that they were creating a new, better society. Drug overdoses and HIV turned that ship around quick.
Maybe it's more accurate to say that the better ideas resist change.

I'm on the fence about the revisionist view that the Ptolemaics were rational at the time, but in a way its optimistic. I have always been suspicious of the "only people in the last 500 years had brains" bias. I wonder if all ages have had that bias?
This is an incredibly interesting point to consider. I would like to say that yes, every age had this kind of a bias, but perhaps that's not true. Life was rather similar during the time of the Roman Republic and the beginning of the Renaissance. The daily life of average people, their wealth and tools weren't that different. They certainly have much less difference then the difference between the start of the Industrial Revolution and today. Perhaps people in previous ages didn't have this kind of a bias because they didn't see such a huge change in people's lives?
One thing that we seem to be adopting as a society is the idea that we need some kind of reasonable evidence for our beliefs. Usually this means that evidence based on the science of nature prevails, but we haven't really been able to push this onto all areas of life. I certainly think that we've managed to cover more fields than in the previous ages though.
Looking at the way most people (including most I know) approach both factual and moral questions, there's no belief in history that seems implausible, from chattel slavery to the humors theory to epicycles to the Inquisition. Most people really don't have the capacity to believe anything but what their social environment tells them to, and it's much more productive to consider the incentives and available information of the narrow few who are capable of doing so.
Hindsight is always 20-20
There’s a reason why I deleted my Twitter years ago; it just is not possible to have civil discourse and well-made arguments in 160 characters (or whatever Twitter’s limits are these days); instead it’s like a bunch of chimpanzees throwing poop at each other.
Scott Alexander recently posted a long entry where he, among other things, misses the kinds of long winded rational arguments places like talkorigins.org had over a decade ago:
