Mormons are quick to change doctrine based on the winds of change.
Two examples:
1. Plural marriage.
2. Views on black folk.
Yes quick to change about plural marriage if you consider almost 150 years as a quick change.
" Views on black folk." has never changed
We are all "brother and Sisters of Our Father in Heaven"
I think you are erroniously referring to priesthood held by blacks which occurred about 50 years ago, under President Kimball.
I think that you have been misinformed...again !
But fear not , as many have been misinformed , ... still !
