Rachel Dolezal caused huge offence by claiming to be of African American descent. Not questioning why that's offensive, but if she sincerely identifies with black culture more than her own, how is she different from a man who 'feels' female? Why should the second example be less offensive to members of the oppressed group in question? Not saying I'm in any way offended by men who 'feel' female or identify as trans but just wondering why I'm more accepting of that then I would be someone like RD? Is it social conditioning or is there another reason?
