Town 21
Watch Now
In the heart of every person with Down syndrome and their loved ones lies a dream of Town 21—an imaginary place where everyone is accepted and loved. Town 21 has no judgmental stares or bullying, and everyone is included. The laws are equal for all. Town 21 is a mental escape for those facing rejection, highlighting the absurdity of a society where fairness and love must be imagined. But NDSS works to make Town 21 a reality by embracing its spirit and working to create a world where everyone feels at home, assured of their human rights, and valued by a more inclusive society. We’re fighting for Town 21: Are You?
