Apparently, if you're black, you can wear your hair any way that you want and if your employer doesn't like it, then it's discrimination.  However, if you're white, then you are subject to the rules of your company as to how you may or may not wear your hair.

But black Americans are the victims of systemic racism.

Bullshit.
