Who is different?

I have heard a few times said that we must pray for those that "are different to us".
It gives me the sense of barriers and of judgement; it seems to say: there is us and
then there are those who are different from us.
Do the people that say this think that they are identical to all the people that they group
themselves with?
This is not even about race or culture, it is about people that are being judged as being
"different" because they are not being understood.
They are not being understood because those people do not really want to understand.
They are faced with their own prejudices and so just decides that some people are "different."

Every single person on earth is completely unique, that is a scientific fact.
Not even identical twins are identical.

"Recent research presented at the 2012 American Society of Human Genetics meeting, however, suggests that identical twins may not be as genetically similar as hitherto suggested. Identical, or monozygotic, twins come from the same fertilized egg. So, at some point during cell division (before 14 days post-conception), identical twin embryos share virtually all of their DNA. During early fetal development, however, identical twins undergo more than 300 genetic mutations, or copy errors, on average. As human cells divide trillions of times during their lifespan, a few hundred genetic mutations could lead to millions or trillions of genetic differences in the DNA of identical twins over the years. Chemical factors can furthermore activate or suppress gene expression, which means that the same subset of genetic material can lead to the formation of different proteins."


 Psalm 139:13-15:
"For you created my inmost being;
you knit me together in my mother’s womb.
I praise you because I am fearfully and wonderfully made; your works are wonderful, I know that full well.
My frame was not hidden from you
when I was made in the secret place.
When I was woven together in the depths of the earth, your eyes saw my unformed body.
All the days ordained for me were written in your book before one of them came to be."

As we know ;culture, nurture, upbringing and other personal circumstance all play a part, but this old fashioned idea that some people are different and "we must pray for them", is
stupid and arrogant.
It is better to pray that God will open our eyes so that we can see our own faults and attitudes that hinders His work in us.
