I was reading an article recently (I don't remember where) pointing out that "diversity" alone doesn't necessarily do anything. Frequently, it ends up being tokenism. It's one thing to hire the requisite black person and (in some places) the requisite woman and the requisite gay person, etc. It's another to have an environment that accepts and welcomes and integrates people who aren't exactly like the people who run things.
I've read posts by trans people in "dude-bro"ish software houses who have the distinct feeling that they are there on sufferance and left out of the more informal decision making processes because they don't fit the company culture.
I don't think that will happen to me when I transition at work. On the other hand, our group and indeed our side of the business (and maybe even everybody more than 5-6 levels below the CEO) seem to be out of the loop on almost everything, so maybe we're all kind of tokenized already.
