Ah. The comment was:

>Right. I made a reference to educational development being retarded due to COVID restrictions and the very people you'd expect to be offended were of course offended.

I misread that, and interpreted "retarded" as being a subjective judgment applied to the restrictions.

That said, the reading "[the process of] educational development has a mental disability" is utterly incoherent, so I still see no reasonable justification for taking offense.
