Seriously? You're gonna make this into a "mixed girl problem"?
Okay, from one mixed girl to the other: stop it. This has nothing to do with you being mixed. Maybe you should re-read your first post. You're contradicting yourself by saying that you don't know what nappy means and at the same time knowing that it is offensive (also the line about Afro-textured hair shows that you do know that the term nappy is a racial slur for aforementioned hair type). That makes no sense.
You are a grown person who can do her own research. We are on the internet - google it.
I am not American either nor have I ever been to the states but I managed to find out about this topic without insulting anyone in the process. There are so many places where you could have looked it up. And for future purposes you should take that to heart.
There is inherently nothing wrong with asking about something you don't understand but your post makes it very hard to sympathise. You don't want Afro-textured hair and we're supposed to tell you that it does NOT look nappy....come on now.
You also do know that mixed people come in all shades and some of us do have kinky hair. I am not saying that being mixed doesn't have it's problems. But I'd argue that hair is one of the lesser ones. If it is even a problem to begin with.
I was initially not going to harshly "attack" you for your question but this "mixed girl problem"-thing just angers me.
I hope you realize that the harsh responses you got where more defensive than attacks on your person.
Remember that most curlies on here had to fight mindsets like yours at some point.
