Yeah, as a person with a diverse racial background from Texas since before it was Texas (relevant cause of the opinion I'm getting to spout), you might be right that there "is no material benefit, ever, from me declaring myself to be white." I personally think race is a wholly made up concept, so it's a bit vexed to add it into how institutions deal with folks. What you're writing made me think about something that's omitted from what you're writing: almost all of the benefits I've had from how folks interpret my race have come from -not- having to say explicitly how my race should be interpreted. So, while I get what you're trying to say, where I live most racism exists in the unspoken assumptions about how people act. As such much of that racial bias is very difficult to point out to people because it's like trying to point out water to fish.
