I did not mean to be aggressive, just direct.

There is no "Lisp community". In this family of languages, there are a bunch of individuals that sometimes form communities around areas of interest or particular fora.

If you looked into Clojure and Elisp, looking into Common Lisp or some Schemes could still be valuable, sure. All of them are in use. You can visit the relevant subreddits or chat channels or mailing lists to "get connected". Maybe even find some meetups or submit pull requests.

As far as I know there are no Emacsen in popular use today except GNU Emacs. There are some editors "inspired" by Emacs that are developed and possibly used by a few. These may be interesting and you may find them usable, but I'm not sure their authors would consider them part of the family of Emacsen just yet.
