No, I'm not at all disturbed by that at all. I understand it on some level. It's difficult to grow up not having someone to look to that looks like you, if that makes sense. But it saddnes me that the person feels that way.
You can be convinced of whatever you want. I have siblings that have 2 black parents (after my biological father remarried), I have siblings, that like me have a Black father and a white mother. I have no issue at all with what the person behind the tweet wishes beyond the fact that she's obviously in pain.
