Red Headed Step Child 

A stepchild might be singled out for abuse. But a red-headed stepchild (who presumably looks like his or her absent birth-parent) might be abused even more because he or she is so obviously different from the other children.

Myles was the red-head step child of the family, he was never invited to the family reunions.

red headed step child 

A bashling. Some one who is singled out for emotional abuse and/or physical abuse. Some one who gets purposely written out of their inheritance. Some one with no birth rights. Some one purposely neglected financially. The unfavored one.

In my father's family I was just a red headed step child.

red headed step-child 

Derives its meaning from the idea that;
1. Red heads are to be avoided
2. That step children are to be avoided.

So the idea of the both combined is doubly hateful
