Well said.

The trouble with social taboos (even ones that exist for good reasons) is that it can be hard to understand who's being polite, and who's just stupid. Many people are stupid about many things, after all, even when there are no reasons to pretend.

Thus it seems valuable that there are places outside of such conventions. The internet has been very good for this -- things once known only by academic specialists are now open to anyone interested. Sometimes you return to polite society able to better decode what people really know.
