Dr Gladden has issues with his identity, and has his own responses and solutions .
It would be interesting if he was writing this in poetry, or creative prose, but an academic making 'I now am' statements in apparently serious prose, is 'interesting' in a different way..
Of course there sometimes seems to be a bit of a golden glow around the people who do not share an oppression - seeing them walking around avoiding the hassle that we have to put up with on a daily basis - or even, if you are disabled, seeing people just walking around and climbing those steps that prevent you from entering a building - and this has to have an impact, and different people are going to respond differently - some with hatred, some with envy, some with a burning desire for justice and equality that makes whatever you are fully respected.
The able-bodied young man bounding up the steps that I struggle with may have serious mental health problems. The white woman who seems so authoritative to Dr Gladden may be the survivor of sexual abuse, or may be about to meet her rapist. The white supremacist thug looking for his next victim won't pause to ponder whether they may identify as white, and therefore should be spared.
There are structural inequalities and injustices in society which unfortunately we can't just identify out of, or in the case of trans-identifying men wanting to be women, identify into. People are entitled deal with their lived experience of structural inequalities in different ways that feel right to them, and this person has responded in a very individual way which will raise eyebrows and hackles on every side.
That's how Dr Gladden feels, and he's entitled to write about it, and I'm inclined to leave it at that rather than generalise from his very personal and distinctive take on being black/white/male/female.
