Because there's nothing wrong with wearing a short skirt and there *is* something wrong with being a rapist. (Jesus fuck, I hope we can at least agree on that.) So where should the focus be? In the person doing nothing wrong, or on the one RAPING people.
There's nothing inherently wrong with naming your child Tyrese or Jin or Ahmend. There is something wrong with being racist. So whose behavior should be focus on changing--the one doing nothing wrong, or the racist who won't hire someone whose name doesn't sound white?
That's what's wrong here. It's not saying, on an individual level, "given that the world has a lot of racists fucks in it, one needs to be thoughtful and consider all implications, unfortunately, when choosing a name for a child. It's terrible that we live in a world where people even have to consider erasing a part of their culture in order to prevent judgement or worse, but that's reality. So it's something to consider." That's not wrong (though it's also worded in a way to make clear that the PROBLEM is someone else's fault.) What's wrong is that a proposed solution to facing racism is for the victims or potential victims to change their perfectly benign behaviors, rather than saying the racists need to change theirs.
Can you really not see the nuances in that?
Would you really say to your mother, if she were raped, "in the future, wear a longer skirt and carry a rape whistle, mom. It will help solve the rape problem and maybe prevent you from being raped again!"? Or would you tell Tyrese and Ahmed, or their moms, "It sucks that it's taking you twice as long to find a job as your non-culturally (non-white) named peers. You should change your names and make sure to give your kids very white-sounding names in order to solve that problem."
Would you say that? And not feel like a massive dickhole? Or might you feel just a touch insensitive if you did?
