[Wingnut]

This is the other one I was looking for (note the year in which this was given).

Here's what President Spencer W. Kimball said:

"Now, the brethren feel that it is not the wisest thing to cross racial lines in dating and marrying. There is no condemnation. We have had some of our fine young people who have crossed the lines. We hope they will be very happy, but experience of the brethren through a hundred years has proved to us that marriage is a very difficult thing under any circumstances and the difficulty increases in interrace marriages. A couple has not committed sin if an Indian boy and a white girl are married, or vice versa. It isn't a transgression like the transgressions of which many are guilty. But it is not expedient. Marriage statistics and our general experience convince us that marriage is not easy. It is difficult when all factors are favorable. The divorces increase constantly, even where the spouses have the same general background of race, religion, finances, education, and otherwise. We are unanimous, all of the Brethren, in feeling and recommending that Indians marry Indians, and Mexicans marry Mexicans; the Chinese marry Chinese and the Japanese marry Japanese; that the Caucasians marry the Caucasians, and the Arabs marry Arabs."
