What you’re arguing against is not the point I was making. My point in this thread is way up there: it replies to someone saying you cannot make the world better without communicating with other humans, by presenting someone who on their own improved the world more than most (if not all) Facebook groups ever will.
When I used the word “limited”, it was clearly in reference to it being an “isolated” specific community and not everyone.
