Discussion about Buddhism in America has sometimes focused on the issue of the visible ethnic divide separating ethnic Buddhist congregations from import Buddhist groups.[77] Although many Zen and Tibetan Buddhist temples were founded by Asians, they now attract fewer Asian-Americans. With the exception of Sōka Gakkai,[6] almost all active Buddhist groups in America are either ethnic or import Buddhism based on the demographics of their membership. There is often limited contact between Buddhists of different ethnic groups.
