I agree with my adopted daughter
What topic do you agree on?
My adopted daughter is black, bi-sexual and feels like an elder sister to the biological children.
It's great that you understand how your daughter feels and that you agree with her. You should tell her that you agree with her so that she knows you can relate to her. This will increase the bond between you both.
I disagree with that. I hate her for being black.
You should try to be more understanding of her black ancestry. You should want to understand her fully and not just partially. It will help your bond with each other.
