Race is a much more fluid, and much less definable attribute than physical gender. Yet it seems that the idea of someone being 100% physically 'white' but identifying as black seems to really put off a lot of people. From the various comments, it would seem that a lot of these same people are completely accepting of the idea of transgenderism.

One common complaint is that Ms. Dolezal lied, and that if she had said that she was born white, but identified as black, then it would have been okay. I don't think that there would be the same anger directed at a person who was born physically one gender but lived as another gender, and didn't go around telling everyone.

So, why the double standard?
