According to this
Charity Data the entire gamut of charity work is to do with promotion of the Baha'i faith. Maybe it's an anomaly.
I have nothing against donating to religious institutions, when they uplift people as much as they do, but there's a difference, in my mind, between direct charity for anyone (like the Red Cross, Food banks, etc.) versus religious donations. I'm sure sometimes those lines do get blurred. The Salvation Army would be one such example. Religious groups also tend to be administrative top heavy in this regard.
