I wasn't talking about mitigating racism, so I'm not sure why you asked that.
My first post was a general observation that the "race" involved in WW2 Japan no longer exists in a manner of speaking.
My second post had nothing to do with racism at all, because it wasn't in response to the OP. It was in response to your post, which also had nothing to do with racism insofar as I could tell.
I'm still really not sure why you're challenging me. But, oh well. Such is the internet...
