 I just expect people to have a basic education about a topic that they
want do discuss in public. That is necessary to have a discussion on
eye-level¹.

I expect people asking questions of other users to provide the commands they want the information from.
Nobody claimed to have an education in the topic. We just commented on a symptom. You, who claim to be the expert, is who has to ask the proper questions.
Don't be uppity.

I think that the local resolver should² also refrain from asking for
AAAA records if the local system doesn't have IPv6, but I don't know
whether this special-case handling is implemented at all. And I'm too
lazy to look that up.
 But all this needs to be taken into account before someone can comment
about speed of one IP protocol compared to the other on a level that
is beyond passing myths.

It just is a perceived fact. On some machines, if an application gets back from the system a list of addresses to try, and tries IPv6 first when there is no actual IPv6 internet connectivity, there is a small delay waiting for the request to fail, and then try the next address in the list.
It doesn't happen to me currently, so asking me to provide information is pointless. But it has happened to me in the past. And I know because the software complained of no route or something.
