Think for a second: why does it matter what specific minority I am? Am I black? A woman? A black woman? Or one of those that doesn't get anywhere close to the media attention these do?
Doesn't matter. Hire me for how I do the job. That's how prejudices are broken. Not by re-affirming prejudices by giving me handicap points.
So, that made me consider why it would even matter, given the source isn't really trustworthy. But really, it probably matters because it gives people a reference point/image in their heads which makes thinking about such things a little easier. But, I'd rather not have readers think reflexively and instead think about how they might react. Not sure if that made sense :)
tldr: I wasn't trying to insinuate anything underhanded in your comment :) I just thought that it might lead people to think a little more if my exact minority wasn't disclosed, rather than (however subconsciously) pattern matching me into a bucket.
