Interesting that you would say that. When I was a missionary in the Taiwan Taipei mission - 1977 to 1979, (then senior apostle) Ezra Taft Benson came to speak at our mission conference.
“Elder” Benson spoke of how there was no blood of Abraham in Asia (contrary to what the bible teaches) and declared that LDS missionaries should not return to Taiwan to marry local Chinese LDS girls. He said “Go back to America and marry a nice white girl so that your parents will have grandchildren they can be proud of”.
He also stated “We are not here to convert the Buddhists. Leave them to their damnation. We are here to convert the Christians”. All of the people I baptized on my mission were Buddhists when I contacted them.
After that conference talk, many elders expressed the sentiment that “if Benson becomes the prophet I will leave the church”.
Well, Benson did become the prophet when Spencer W. Kimball died. Several of those missionaries eventually did leave the LDS church ( a few subsequently became Catholic) but I’m sure that most did not.
