Intended as abbreviation, but fair point. And no slight to any actual rattus rattus, if any are acasually lurking from the civilization they will build long after humans wipe themselves out. Impressive animals.

Reasonable explanation of why they write this kind of stuff, thanks. And of course such a culture attracts those who like to write such.

For my part I didn’t read the “rats” bit as (intending to be a) dehumanising (use), but instead as the short form of the name as they themselves use it too

But the possibility from overloaded context doesn’t help, I’ll definitely agree on that - if someone read this without some context knowledge, it could def read badly
