There were some racist incidents at Baha'i gatherings

...the New York City Bahá’í community had dedicated itself to regularly disrupting the Black/White color line, inclusive of inter-racial teaching efforts in Harlem. Toward that end, there was a marked increase between New York area Bahá’ís and groups like the NAACP and Urban League (Buck 2012; Hogenson 2022). Yet, intra-Black issues and unintentional slights proved weighty matters. While “the Bahá’ís naturally associated with all kinds of people, including immigrants from the Caribbean and Africa,”wrote historian Kathryn Hogenson, “… these groups of Blacks were not welcomed by Blacks from the United States—an issue within Harlem that spilled over into the Bahá’í community. It also had to deal with reports of incidents at Bahá’í gatherings which were perceived by community members to be racist” (Hogenson 2022, pp. 175–176).
