How they converted the innocent people?

Baha'is went from house to house up and down the road, asking blacks "if they believed in peace, brotherhood, and equality." If they answered: "yes", they were told that they were Baha'is and should Sign a declaration card. Seeberger claims that these blacks were not told of any restrictions resulting from membership in the Faith and were led to believe that they would benefit from educational, scholarship, or welfare programs if they became Baha'is.
