Romney
calling Trump remark about Judge Gonzalo Curiel racist could be that it struck
home on a personal basis. Romney's father, George, was born in Chihuahua, Mexico, and so was his
grandfather, Roman. ... You didn't know that Mitt Romney was half-Mexican? ...
Technically, Romney is just as "Mexican" as former New
Mexico Gov. Bill Richardson, who was born of a Mexican mother and American
father.

And Romney knows about racism the Mormon Church was racist until 1978. However LDS was racist against blacks.
From 1849 to 1978, The Church of Jesus Christ of Latter-day Saints (LDS Church) had a policy against ordaining black men to the priesthood, and
forbidding black men and women from taking part in ceremonies in LDS
temples. Associated with this policy were various statements
by church leaders tying the policy to their view of scripture, and opining that
black men and women had inherited the curse of Ham. In
1978, the church's First Presidency declared in a statement known as "Official Declaration 2"
that the ban had been lifted as a result of a revelation from God.
Fundamentalist Church of Jesus Christ of Latter-Day Saints position
In 2005, the Intelligence
Report published the following statements made by Warren Jeffs,
President of the Fundamentalist
Church of Jesus Christ of Latter-Day Saints:
·
"The black race is the people through which the devil has
always been able to bring evil unto the earth."
·
"[Cain was] cursed with a black skin and he is the father
of the Negro people. He has great power, can appear and disappear. He is used
by the devil, as a mortal man, to do great evils."
·
"Today you can see a black man with a white woman, et
cetera. A great evil has happened on this land because the devil knows that if
all the people have Negro blood, there will be nobody worthy to have the
priesthood."
·
"If you marry a person who has connections with a Negro,
you would become cursed."[57]
