My own take on this is that this isn't something extending to fair use. If you're translating judiciously trimmed portions of a text for whatever explication you're engaged in that is likely to be totally fine. Slapping vast passages or complete versions is beyond the pale though.
@DNA@durf You're in the clear* if you want to privately share the text with readers you know personally, but I would shy away from posting it anywhere public-facing unless you have permission from the original author.
* as far as I know, I am not a lawyer, I am not your lawyer, etc. etc. etc.
@hannu_ikonen ugh, such garbage. So glad to be in a country where the 90+% are not morons and still mask up on public transport, and almost 100% have them on in medical institutions.
