Long story, I'm staying anonymous per my sister asking.

Okay, Me and my sibling are all adopted from a Chinese mother, caucasian father.

All of the siblings are from different walks of life. I'm white, My sister is African American.

My sister, met and fell in love and then eventually married a man will call Devin. Hes a black man, mid 40s while my sister is 26.

Devin always poked fun at my sister, said she was an inside out oreo, that shes not a "real" black woman. That she talks to white, she doesn't dress black or act black etc. But she pushed that aside as joke.

Once she got pregnant ( twin boys) it got worse. She picked the names David and Matthew for their sons. He flipped out, basically calling her a wanna be white bitch, that's shes a disgrace his children would never bare "Cracker" names and then said they aren't allowed around our family because we are "white" and that she needs to open her eyes and see how they look at her as nothing but another "N" on the street ( which isn't true my parent raised us all equally )

My sister is over it, and she want to divorce and leave him. She wondering if she can use this as emotional of mental abuse? She had 100s of messages calling her names and poking fun of our family.
