Welcome back to September and the many special days this month holds in important traditions (Jewish New Year..Rosh Hashanah, and A Day of Atonement, Yom Kippur) and much more. Many faith communities have worth while services and programs to benefit a community and many are also online. See for instance The Brooklyn Unitarian Church or The Apostolic Baptist Church in Brooklyn NY.
That said, other events to consider working into one's repertoire for getting cenbererd and collaborating with peaceful efforts include Geozuwa (see him online and maybe in person in NYC, MA or FL), David Adelson
