Yes. To gwern (verb) it, to reconstruct it from quotes according to the Pareto principle:
...Let’s start with a test: Do you have any opinions that you would be reluctant to express in front of a group of your peers?
If the answer is no, you might want to stop and think about that. If everything you believe is something you’re supposed to believe, could that possibly be a coincidence? Odds are it isn’t. Odds are you just think whatever you’re told...
If you believe everything you’re supposed to now, how can you be sure you wouldn’t also have believed everything you were supposed to if you had grown up among the plantation owners of the pre-Civil War South, or in Germany in the 1930s—or among the Mongols in 1200, for that matter? Odds are you would have...
What can’t we say? One way to find these ideas is simply to look at things people do say, and get in trouble for.
Of course, we’re not just looking for things we can’t say. We’re looking for things we can’t say that are true, or at least have enough chance of being true that the question should remain open. But many of the things people get in trouble for saying probably do make it over this second, lower threshold. No one gets in trouble for saying that 2 + 2 is 5, or that people in Pittsburgh are ten feet tall…
This won’t get us all the answers, though. What if no one happens to have gotten in trouble for a particular idea yet? What if some idea would be so radioactively controversial that no one would dare express it in public? How can we find these too?
Another approach is to follow that word, heresy...
We have such labels today, of course, quite a lot of them, from the all-purpose “inappropriate” to the dreaded “divisive.” In any period, it should be easy to figure out what such labels are, simply by looking at what people call ideas they disagree with besides untrue. When a politician says his opponent is mistaken, that’s a straightforward criticism, but when he attacks a statement as “divisive” or “racially insensitive” instead of arguing that it’s false, we should start paying attention.
So another way to figure out which of our taboos future generations will laugh at is to start with the labels. Take a label—“sexist”, for example—and try to think of some ideas that would be called that. Then for each ask, might this be true?...
I can think of one more way to figure out what we can’t say: to look at how taboos are created. How do moral fashions arise, and why are they adopted?
Moral fashions more often seem to be created deliberately. When there’s something we can’t say, it’s often because some group doesn’t want us to.
The prohibition will be strongest when the group is nervous...
To launch a taboo, a group has to be poised halfway between weakness and power. A confident group doesn’t need taboos to protect it. It’s not considered improper to make disparaging remarks about Americans, or the English. And yet a group has to be powerful enough to enforce a taboo. Coprophiles, as of this writing, don’t seem to be numerous or energetic enough to have had their interests promoted to a lifestyle...
Some would ask, why would one want to do this? Why deliberately go poking around among nasty, disreputable ideas? Why look under rocks?...
...If, like other eras, we believe things that will later seem ridiculous, I want to know what they are so that I, at least, can avoid believing them...
The most important thing is to be able to think what you want, not to say what you want. And if you feel you have to say everything you think, it may inhibit you from thinking improper thoughts. I think it’s better to follow the opposite policy. Draw a sharp line between your thoughts and your speech. Inside your head, anything is allowed...
The trouble with keeping your thoughts secret, though, is that you lose the advantages of discussion. Talking about an idea leads to more ideas. So the optimal plan, if you can manage it, is to have a few trusted friends you can speak openly to. This is not just a way to develop ideas; it’s also a good rule of thumb for choosing friends...
...Who thinks they’re not open-minded? Our hypothetical prim miss from the suburbs thinks she’s open-minded. Hasn’t she been taught to be? Ask anyone, and they’ll say the same thing: they’re pretty open-minded, though they draw the line at things that are really wrong. (Some tribes may avoid “wrong” as judgemental, and may instead use a more neutral sounding euphemism like “negative” or “destructive”.)...
...And pay especially close attention whenever an idea is being suppressed. Web filters for children and employees often ban sites containing pornography, violence, and hate speech. What counts as pornography and violence? And what, exactly, is “hate speech?” This sounds like a phrase out of 1984.
Labels like that are probably the biggest external clue. If a statement is false, that’s the worst thing you can say about it. You don’t need to say that it’s heretical. And if it isn’t false, it shouldn’t be suppressed. So when you see statements being attacked as x-ist or y-ic (substitute your current values of x and y), whether in 1630 or 2030, that’s a sure sign that something is wrong. When you hear such labels being used, ask why...

Add “politically correct” to the set of possible x and y and we are in agreement. This was the point of my original comment on the matter.
Saying things violate Paul Grahm’s principle isn’t used here to dismiss ideas, only to, as you said, put the burden of proof on them as being prima facie false. I don’t think that “heretical” was quite the same way, nor are “racist” and “fascist”, etc.
I would never say “prima facie proves” so maybe we are using some words to express very different concepts.
