Having an "African-American" section isn't saying "African Americans can ONLY USE THESE!", it's saying "You're more likely to find these names on an African-American person"-- it's a usage category. It'd be surprising to meet a white woman named Nikeisha; it wouldn't be surprising on a black woman because Nikeisha is an African American name.
It's just like, it'd be surprising to meet a black woman, or a white woman, named Junko. It wouldn't be surprising to meet a Japanese woman named Junko, because it's a Japanese name. That's why it's listed as Japanese on this site.
I'm sorry people in your life don't grasp that, but we're not the ones you should be mad at.
