This is not possible.
When you previously mentioned "nice communities", I thought that meant specific javascript forums. Now I see you meant to drive the undesirables out of entire Javascript language completely and force them into another language.
>You had been saying that even that shouldn't be bothered with.
I've never said this. I've never suggested that people shouldn't strive to have well-behaved communities that encourages constructive feedback. In the forums I moderated, negative rant posts were not allowed and deleted.
However, I see the confusion in interpreting my posts now. You and Mouq are focused on the "making a better world" angle. My posts were describing something else: the build up of anger about <topic> will always exist to frustrate people like JK regardless of the efforts to make a friendlier community. (E.g. see multi-decades history of discourse about C++/Java/Lisp/etc/etc)
