I wish the Church would tackle racism and nationalism with the same energy it devotes to sex. 

It’s not difficult to envision.  Just take every resource the Church of Jesus Christ of Latter-day Saints currently spends defending chastity and reallocate them to anti-racism.  When we’re inevitably challenged for being too “political,” emphasize the great moral need for social policies which recognize the divine worth of every soul.    

We have the foundation to accomplish this.  In October 2020 President Nelson pleaded with us “to promote respect for all of God’s children.”  The Prophet “grieved that our Black brothers and sisters the world over are enduring the pains of racism and prejudice.”  He then called “upon our members everywhere to lead out in abandoning attitudes and actions of prejudice.”
