I suspect this will fail, not out of racism against each other, but because of racial preference in their religious experience.
That is, predominantly white religious services tend to be calm and reserved, with limited and ritual only congregational involvement. At length there are times where it is as quiet as a library. It is a subdued and thoughtful experience.
But predominantly black religious services tend to be rather loud, boisterous, and enthusiastic. The congregation is involved in the ceremony and even the sermon.
Of course there is considerable variation in all of this, but it is the general preference of the people involved. Yet an effort to integrate the two cultures will prove unsatisfactory to either group, far less enjoyable that what they were raised with.
Moore knows that. He is also pro-amnesty. People like him says such things as a way to portray themselves in what they think is a more acceptable, morally superior, enlightened, levels. The implications of his statement is belittling to Baptists.
