Because they have been stuck in a caravan??!!!
Identical twins have exactly the same genotype, including sex.
It is not possible to have identical twins of various genders. Identical twins are all the time of a similar sex since they frame from a solitary zygote that contains either male (XY) or female (XX) sex chromosomes. Children boy/girl twins can't be identical twins. A lady's odds of having identical twins are not identified with age, race or family history.
The Social Gospel movement influenced the Civil Rights movement because it applied Christian values and ethics to social issues. Race and the color barrier between white people and black people at the time was a huge issue that this movement focused on, among other issues of course.
As you know, MLK was arguably the most influential public figure in the Civil Rights movement. In a way he was also a big part of the Social Gospel movement in the sense that he was deeply religious, and many of his ideas for social justice were rooted in Christianity.
Hope this answer helps!
