Why the split from .world? People are free to be on whatever instance they choose, of course.
This community (as a whole under the "stop drinking" banner) is not huge and probably wouldn't benefit from multiple communities at this time.
IMHO, a unified group is probably much easier for Lemmy newbies.
(If you would like to continue this discussion privately, we can. This is not an ideal forum for "Lemmy politics", me thinks.)
